A multi-protocol wireless communication baseband transceiver includes a baseband transmit processing module and a baseband receive processing module. The baseband transmit processing module includes an encoding module, an interleaving module, a plurality of symbol mapping modules, a plurality of domain conversion modules, a plurality of cyclic prefix modules, a plurality of compensation modules, and a control module that is operably coupled to produce preamble set up information and payload set up information based on a mode of a plurality of protocol modes. The baseband receive processing module includes a plurality of receive compensation modules, a plurality of cyclic prefix removal modules, a plurality of receive domain conversion modules, an equalizing module, a plurality of demapping modules, a deinterleaving module, a decoding module, and a receive control module that is operably coupled to determine the mode from the plurality of protocol modes and the compensation control signals based on the at least one compensated stream of symbols.
