Abstract :
In this paper, a spatially multiplexed orthogonal frequency division multiplexing multiple input multiple output (SM-OFDM-MIMO) IEEE 802.11n system is assumed. The 802.11n system performance is comparatively analyzed implementing either linear minimum mean squared error (MMSE) receiver or MMSE ordered successive cancellation (MMSE/OSIC) receiver with both hard and soft decision Viterbi decoding over a canonical quasi-static flat fading Rayleigh MIMO channel. We have concluded that the relative performance gains due to the MMSE OSIC receiver depend strongly on the modulation code scheme (MCS), number of transmit/receive antennas and spatial stream ordering methodology used in the MMSE/OSIC receiver.
