Abstract(in English) | In this paper, we propose a novel simplified viterbi equalizer for 64QAM signals applied to high symbol rate FWA systems. Reduced complexity and performance improvement are achieved by following two approaches. First one is a reduction of the number of survival paths, taking advantage of a large D/U which is common in LOS (line of sight) communications. Second one is an additional replica making of next candidates to maximum likelihood one. It was confirmed that complexity of proposed viterbi equalizer is reduced without degrading the performance by computer simulations. |
