Abstract :
In this study, error performance analysis and simulation results are provided for the weighted erasure decoding (WED) of binary linear block codes on Q-ary output channel. In particular, the optimum channel quantizer for WED is derived and compared with WED designed based on the cutoff rate criterion, as traditionally proposed. Simulations are conducted for the (64, 42, 8) Reed-Muller (RM) code on 4-ary and 8-ary output channels. For Q=8 and the bit error rate (BER) 10-4, the WED with optimum quantizer has a 0.65 dB coding gain over the WED with cutoff rate quantizer and a 1.0 dB coding gain over algebraic decoding
