An adaptive trellis coded modulation (TCM) and bit-interleaved coded modulation (BICM) scheme is proposed for ordered MIMO-OFDM channels, derived through singular value decomposition (SVD) based eigen-beamforming and subchannel grouping techniques. By deriving bit-error-rate (BER) upper bound of TCM and BICM for the ordered channels, it is observed that TCM is better than BICM for the grouped channels...
