Abstract

The present invention comprises a system and method for gain control of individual narrowband channels using a wideband power measurement. The present invention comprises a transmit power tracking loop (202) which controls the power of the transmitted signal by controlling the gain applied to the signal. The function of the transmit power tracking loop (202) is to measure power (234, 236), accept commands for power adjustment, and adjust the power (226). Gain control is performed by producing an error signal (224, 228) using the comparison of measurements (224) of a total of estimated powers of each narrowband signal (218, 220, 222) and a measurement of the modulated wideband signal (234, 236). In addition, open loop control is performed by accepting open loop commands generated by an algorithm.
