We present an improved V-BLAST receiver that cancels co-channel interference (CCI), based on reliability normalization over frequency-selective channels, in log-likelihood ratio (LLR) sense. The performance has been evaluated in the exponential decay channel model with various normalized rms delay spread and different filter taps. It is also compared with the ordered successive interference cancellation-decision feedback equalizer (OSIC-DFE). Simulation results show that the proposed receiver outperforms the OSIC-DFE, especially when the filter taps are short.
