This paper proposes space division multiplexed coded orthogonal frequency division multiplexing (SDM-COFDM) scheme using inter-channel interference canceller for multi-input multi-output (MIMO) channels. It reduces the degradation due to inter-channel interference in SDM transmission with a feed-forward canceller multiplying the received symbols by the estimated propagation inverse matrix for each OFDM subcarrier. Moreover, the proposed likelihood-weighting scheme, which is based on each subcarrier's signal-to-noise power ratio (SNR), enhances the error correction performance or soft decision Viterbi decoding. Computer simulation shows that the SDM-COFDM scheme achieves more than 100 Mbit/s per 20 MHz in frequency selective fading environments with the same carrier-to-noise ratio (CNR) as the single channel COFDM. |
