Abstract
A method of applying decision feedback to the decoding of IS-95 uplink fram es is described. Bit values which have been determined by a Viterbi decoder are used to modify the probability measures of convolution coded bits whic h have not yet been used by the decoder, in order to improve bit error rate (BER) performance. The method is analyzed from a probabilistic viewpoint a nd simulation results are presented.
