This invention addresses the need for new more efficient embodiments and implementation architectures of reconfigurable, adaptable, interoperable multimode ultra wideband -ultra narrowband(UWN) systems as well as a class of broadband wireless, broadband wireless access (BWA) and other spectral and power efficient communication systems. The BWA systems, disclosed herein include new implementation architectures and new “hybrid” embodiments for WCDMA, WiMAX, Wi-Fi, IEEE 802.11 and other IEEE specified systems. Local Multipoint Distribution Systems, other point to point systems and Multipoint Distribution Services (MDS) will need more efficient, reduced size interoperable Multimode Multiple Input Multiple Output (MMIMO) hybrid operation, disclosed herein.
A network which incorporates UWB and UNB or other combinations of communications and or broadcast systems, is designated here as a “hybrid” system or “hybrid” network. While prior art UWB systems, broadband systems, systems known as IEEE 802 standardized systems , WI-FI and/or Bluetooth provide communications for short distances some of these systems are not efficient for longer range/longer distance applications.
While spectrally efficient, narrowband and Ultra Narrow Band (UNB) systems are suitable for short as well as longer distances there are no disclosed embodiments for cost efficient-simple reconfigurable, interoperable communication and broadcasting system architectures, baseband, intermediate frequency (IF) and radio frequency (RF) implementations for Bit Rate Agile (BRA) systems, Adaptive Modulation and Coding (AMC) in case of UWB and UNB systems and the connection of these systems into an operating network. Processing the data signals, clock signals, and/or carrier waveforms of UWB, of UNB and of a class of other systems leads to shaped radio-frequency (RF) waveforms and wavelets. With Multiple Input Multiple Output (MIMO) diversity and protection system configuration the performance and capacity of these “hybrid” UWB and UNB systems may be further enhanced. For such systems more efficient and simpler architectures and implementations are disclosed.
In prior art patents and in other published documents and articles the aforementioned sets of systems were invented, studied and investigated separately from each other and joint-hybrid efficient and seamless, adaptive Modulation Format Selectable (MFS) and Bit Rate Agile(BRA) operation and joint embodiments of systems which operate as Adaptive Modulation and Coding (AMC) in flexible agile UWB and UNB systems in conjunction with other wireless and wired (cable, telephone, fiber optics) systems such as 2nd generation wireless systems, such as GSM systems, CDMA systems, 3rd generation cellular systems and 4th generation wireless and cellular systems , including broadband systems were not disclosed.
One set of communications systems contains highly spectral efficient, narrowband, very narrowband and ultra narrowband (UNB) systems; an other set contains broadband, wideband and ultra wideband (UWB) systems. Combinations and variations of these two sets of systems are designated herein with the generic term/acronym:Ultra wideband—ultra narrowband(UWN) systems.
The most important objectives of wireless communications, broadcasting, telemetry, location based systems GPS (Global Positioning System), Radio Frequency Identification systems (RFID), internet browsing infrared and in general “radio” systems as well as “wired” systems include: power and bandwidth or spectrum efficiency combined with robust Bit Error Rate (BER) performance in a noisy and/or strong interference environment. These Radio Frequency (RF) system objectives are specified in numerous systems including wireless communications and cellular systems, satellite systems, mobile and telemetry systems, broadcasting systems, cable, fiber optics and practically all communication transmission systems. Here we are using the term “Radio Frequency” (RF) in its broadest sense, implying that we are dealing with a modulated signal. The RF could be, for example, as high as the frequency of infrared or fiber optic transmitters; it could be in the GHz range, e.g., between 1 GHz and 300 GHz, or it could be in the MHz range, e.g. between about 1 MHz and 999 MHz or just in the kHz range, such as used in telephony modems. The term RF could apply to Base-Band (BB) signals, to Pulse Position Modulated(PPM) signals, to Quadrature Modulated (for short “QM” or “QMOD”) and to FM or AM or hybrid modulated signals, to non-quadrature modulated signals, or to un-modulated Carrier Wave (CW) signals or waveforms.
The cited publications, patents, pending patents and other published documents, reference numbers [1-31 ], and the references within the aforementioned publications contain definitions and descriptions of many terms used in this new patent disclosure and for this reason these “prior art” terms and definitions will be only briefly, on a case by case basis highlighted.
While the majority of prior patents and publications disclose systems which have a spectral efficiency of less than about 10 b/s/Hz [such systems include GMSK, BPSK,QPSK, QAM (e.g. 16-QAM; 64 QAM), Pulse Width Modulation (PWM), Pulse Position Modulation (PPM) and Pulse Duration Modulation methods] there is prior art which discloses implementations which could attain considerably higher spectral efficiencies, i.e. more than 10 b/s/Hz.
H. R. Walker's patents, references [1-5] and Feher's patent Ref.  describe information signal transmission methods which could attain ultra high spectral efficiencies of more than 10 b/s/Hz, designated herein as ultra narrowband(UNB) or ultra spectral efficient systems.
While the aforementioned issued patents and publications describe material of a background nature, they do not describe or suggest the subject matter of the present patent.
Prior to the description of the current invention, a brief review and highlights of prior art, contained in the description of
This implementation from Feher's U.S. Pat. No. 6,198,777, Ref. No.  is also designated herein as a Feher '777 processor, Feher Keying (FK) Modulation and Demodulation(modem)-system It is suitable for implementation of a part of ultra narrowband (UNB), ultra wideband (UWB) embodiment and combinations of ultra wideband—ultra narrow band(UWN) systems, also designated herein as “hybrid” systems or hybrid networks. The UWN and other hybrid systems, disclosed in the current invention are suitable for Adaptive Modulation and Coding (AMC).
This invention discloses new, efficient embodiments and implementation architectures of reconfigurable, adaptable, interoperable broadband wireless, multimode ultra wideband—ultra narrowband(UWN) systems as well as a class of broadband and other spectral and power efficient communication systems.
A network which incorporates UWB and UNB or other combinations of communications systems is designated here as a “hybrid” system or “hybrid” network.
Processing the data signals, of clock signals, and/or carrier waveforms of UWB, of UNB and of a class of other systems leads to shaped radio-frequency (RF) waveforms and wavelets. Multiple Input Multiple Output (MIMO) diversity and protection system configuration the performance and capacity of these “hybrid” UWB and UNB systems may be further enhanced. For such systems more efficient and simpler architectures and implementations are disclosed.
Specific Objectives of this invention include:
A 1st objective of this invention is to disclose implementations and embodiments which shape waveforms, wavelets, symbols, Radio Frequency(RF) cycles of previously disclosed non-shaped signals by means of optional TCS and/or LR processors and filters. Such shaping improves the spectral characteristics and or other performance parameters the system and leads to, in several cases simpler implementation architectures.
A 2nd objective is to process and generate UNB and UWB signals which have Modulation Format Selectable (MFS) waveforms or wavelets and are suitable for hybrid operation, diversity and protection systems including a new generation of Adaptive Modulation and Coding (AMC ), Multiple Input Multiple Output (MIMO) systems which are interoperable with existing wireless systems, such as cellular GSM, GPRS, EDGE and CDMA and W-CDMA systems as well as with other conventional and broadband wireless and telephony systems.

These selectable bit rates are designated as Clock Rates or Clock of the Control Data “CLC” signals. The CLC rates are in some embodiments integer multiples, sub-integer multiples or fractions of the data rate clock CLD, while in other embodiments the CLC rates are “not related” to the CLD rate; here the term “not related” to refers to a CLC rate which is not derived from the CLD signal, that is, it is in a free running operation and or asynchronous with the CLD rate. In some exemplary embodiments the CLD rate equals the CLC rate, while in other embodiments the CLC rate is four(4) times, or eight(8) times or, one thousand (1000) times, or seven and one third (7and ⅓) times higher than the CLD rate or it is a fraction of the CLD rate. The CLC and CLD signals are provided through Unit 11.4 the Adaptive Modulation and Coding (AMC) unit, as processed control signals to control the operation and signal selection of units 11.5,11.6, 11.7, 11.8, 11.9 and 11.10. Unit 11.4 is an Adaptive Modulation and Coding (AMC) unit; this unit is also designated as Adaptive Coding and Modulation (ACM) unit. Unit 11.4 processes received signals from Unit 11.3 and provides them to the Adaptive RF frequency and wave generation unit 11.l and to processor unit 11.7. The outputs of the AMC contain data signals, control signals, clock signals and other signals (e.g. overhead signals/bits, pre-amble signals, known also as preamble bits or preamble words, signal quality monitor signals bits or chips). Adaptive RF frequency and wave generation unit 11.5 provides RF frequency agile or flexible RF waveforms to leads 11.6. One or multiple leads 11.6 are connected to processor unit 11.7. Within unit 11.7 under the control of the AMC, unit 11.4 processed and/or generated signals and/or under the control of the CLD rate or CLC rate clocks, one or more than one (one or multiple) signals are connected and/or processed and connected to leads 11.8. Selection or combinations of Leads 11.6 and 11.8 are controlled by the output signal or output signals of unit 11.4 the AMC processor. Element 11.7.1 represents a connection between the input and output of processor 11.7. Element 11.7.2 is a digital and or analog signal processor or filter or a hybrid processor and filter which provides signal processing, shaping or filtering functions. Element 11.7.3 is an attenuator or amplifier, or unit gain connector which changes (modifies) the amplitude of the incoming signal and provides an amplitude modified output. Element 11.7.4 is a signal inverter; Element 11.7.5 is a signal inverter and amplitude modification device; Element 11.7.6 is a signal conditioner and or filter. This signal conditioner and/or filter element includes optional phase shifters, time delays and or switch components. The switch component of element 11.7.6l connects or disconnects(disables) the signal path between the input and output ports of element 11.7.6. If in a particular time (e.g. during a specific bit duration or a fraction or multiple bit durations) the said switch component is in one of its positions designated as ON, then the signal is forwarded to the output port, while for the other position of the switch designated as OF, the signal between input and output of element 11.7.6 is not connected. The AMC, Unit 11.4 provided control signals select or combine one or more of the unit 11.7 processed signals, processed by one or more of the aforementioned elements of unit 11.7, and provides these processed signals, through the selected leads 11.8 for subsequent amplification in unit 11.9 antenna selection or splitting combining in selector or splitter unit 11.10. One or multiple antennas, illustrated by units 11.11 and 11.12 are used for signal transmission. In an illustrative embodiment of
In an other embodiment of this invention, for each data signal (data bit or data symbol) representing a one (1) state one(l) RF cycle is provided through element 11.7.1 to the transmit amplifier 11.9, while for each data signal representing a zero (0) state one (1) RF cycle is disconnected, that is in element 11.7.6 it is not connected to transmit amplifier 11.9. This case is referred to as Missing Cycle Modulation (MCM); the MCM has Missing Cycles(MCY) and or Missing Chips (MCH), i.e. not transmitted cycles (disconnected cycles or disconnected fractions of cycles) in the transmitted signals. In
In an other embodiment of this invention, for each data signal (data bit or data symbol) representing a one (1) state eight (8) RF cycles are provided through element 11.7.1 to the transmit amplifier 11.9, while for each data signal representing a zero (0) state one out of eight RF cycles has its output phase inverted (relative to the input phase), or has its phase modified (relative to the input phase); these phase inversion or phase reversal and phase modification processes are implemented in element 11.7.5. These cases are designated as Phase Reversal Keying(PRK) and Phase Modification Keying(PMK) respectively. Illustrative examples of Phase Reversal Keying(PRK) modulated signals are shown in
One of the structures of this invention generates for one state data different waveforms than for zero state data, such as illustrated in
Variations and combinations of spread spectrum processors with ultra wideband or broadband processors and ultra narrowband processors lead to a new set of hybrid systems. Such hybrid systems are contrary to conventional communication systems and prior art technologies. While prior art systems disclose certain elements of this new set of hybrid systems, such as the embodiments of ultra narrowband systems, embodiments of ultra wideband systems and embodiments of spread spectrum systems, the prior art does not teach and it does not anticipate the use of these systems in a hybrid or combined mode as described in the current disclosure.
Unit 19.7 contains one or multiple prior art spread spectrum processors and/or one or more prior art spread spectrum modulators. Prior art spread spectrum processors and modulators include Direct Sequence Spread Spectrum(DSSS), Code Division Multiple Access (CDMA), Frequency Hopped Spread Spectrum(FHSS) and combinations, variations of other spread spectrum systems.
