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 hybrid decoder (HD) for LDPC codes in the presence of additive white Gaussian noise is proposed. This HD employs a min-sum belief propagation (BP) decoding to correct errors, combined with erasure iterative decoding. Whenever BP decoding fails, its output is modified and artificially created erasures are introduced. The proposed HD employs an overall reduced number of iterations and achieves a similar...
