The system (900), transmitter (700), receiver (800.a 800.b), and method of the present invention provide a technique to code data bits into symbols using TCM, MLCM or BIMLCM before the symbols are placed in an SCBT block. Generally, TCM, MLCM, and BIMLCM do not have good performance over the frequency selective channels. However, since the frequency domain equalization of SCBT will flatten the channel, the use of TCM, MLCM and BIMLCM can provide significant gain. Furthermore, since some of the bits are left uncoded, the speed requirements on the encoder and decoder can be relaxed. This feature is especially important for the very high data rate systems.
