Abstract

In this paper, a study on the design and implementation of uniform 4-level quantizers for soft-decision decodings for binary linear codes is shown. Simulation results on quantized Viterbi decoding with a 4-level quantizer for the (64, 42, 8) Reed-Muller code show that the optimum stepsize, which is derived from the cutoff rate, gives an almost optimum error performance. In addition, the simulation results show that the case where the number ofoptimum codewordsislarger than the one fora received sequence causes non-negligible degradation on error performance at high SN ratios of E_b/N₀.
