| Abstract;This paper describes a simple SDM-COFDM (space division multiplexed, coded orthogonal frequency division multiplexing) scheme for MIMO (multiple input multiple output)-based broadband wireless access. The proposed scheme reduces inter-channel interference with a simple feed-forward canceller by using a new space-time coding preamble. Moreover, the proposed likelihood weighting based on the signal-to-noise power ratio improves the soft decision error correction performance. The proposed SDM-COFDM scheme with 2*2 antennas can double the transmission bit rate to more than 100Mbit/s per 18MHz by using 64QAM with a coding rate of 3/4 in frequency selective fading environments.
