Abstract :
Word error rate (WER) performance with soft decision decoding of linear block codes using a trellis is investigated in a Rayleigh fading channel. The signal envelopes corresponding to each bit in a received block are sampled and used for estimating the reliability of the bit. The WER performance is evaluated via laboratory experiments using Hamming (7, 4) code. A great improvement in WER performance can be achieved over conventionally-used minimum distance decoding
