1. A multiple protocol wireless communication baseband transmit processing module capable of multiple input multiple output (MIMO) comprises:

  • control module operably coupled to produce preamble set up information and payload set up information based on a mode of a plurality of protocol modes;

    encoding module operably coupled to;

    encode preamble data in accordance with the preamble set up information to produce encoded preamble data; and

    encode payload data in accordance with the payload set up information to produce encoded payload data;

    interleaving module operably coupled to;

    interleave the encoded preamble data in accordance with the preamble set up information to produce at least one stream of interleaved encoded preamble data; and

    interleave the encoded payload data in accordance with the payload set up information to produce at least one stream of interleaved encoded payload data;

    a plurality of symbol mapping modules operably coupled to;

    map, in accordance with the preamble set up information, the at least one stream of interleaved encoded preamble data to at least one stream of frequency domain preamble symbols; and

    map, in accordance with the payload set up information, the at least one stream of interleaved encoded payload data to at least one stream of frequency domain payload symbols;

    a plurality of domain conversion modules operably coupled to;

    convert, in accordance with the preamble set up information, the at least one stream of frequency domain preamble symbols into at least one stream of time domain preamble symbols; and

    convert, in accordance with the payload set up information, the at least one stream of frequency domain payload symbols into at least one stream of time domain payload symbols;

    a plurality of cyclic prefix modules operably coupled to;

    add, in accordance with the preamble set up information, a cyclic prefix to the at least one stream of time domain preamble symbols to produce at least one stream of preamble symbols; and

    add a cyclic prefix to the at least one stream of time domain payload symbols to produce at least one stream of payload symbols; and

    a plurality of compensation modules operably coupled to;

    compensate the at least one stream of preamble symbols to produce at least one stream of compensated preamble symbols; and

    compensate the at least one stream of payload symbols to produce at least one stream of compensated payload symbols.
