Abstract
The soft output Viterbi algorithm (SOVA) is used for data detection in indoor wireless channels representative of the JTC and wireless local area network (WLAN). The performance of SOVA-SOVA permutation as an equalizer followed by a decoder is evaluated by simulation experiment. The performance does not improve much for more than three iterations in these ISI channels. The results obtained for 1 dB to 4 dB bit energy to noise power approach the coded AWGN performance by the end of the third iteration
