초록
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 ms 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 performance of the proposed receiver with (2,1) is close to OSIC-DFE with (6,3) at normalized ms delay spread 0.5 symbol periods.
