1. A method of processing data for transmission in a wireless multi-antenna orthogonal frequency division multiplexing (OFDM) communication system, the method comprising:

  • coding traffic data in accordance with a coding scheme to obtain coded data;

    interleaving the coded data in accordance with an interleaving scheme to obtain interleaved data;

    symbol mapping the interleaved data in accordance with a modulation scheme to obtain a stream of data symbols;

    forming at least one pair of data symbols from the stream of data symbols; and

    processing each pair of data symbols to obtain two pairs of transmit symbols for transmission from a pair of antennas, wherein each transmit symbol is a version of a data symbol, and further wherein the two pairs of transmit symbols are to be transmitted over at least one OFDM subband, and also further wherein the OFDM communication system is capable of adjusting the total number of available subbands.
