It is confirmed that as the number of symbols of observe sequence increases, SER performances show good approximation to that of the ideal coherent detection by computer simulation. Then, we apply M algorithm to reduce the number of tree path search and can increase the number of symbols of observe sequence. It is confirmed that with the M algorithm the calculation of the likelihood function becomes much simpler and as more the number of symbols of observe sequence increase, SER performances shows even closer to that of the ideal coherent detection.}, title = {フェージング通信路における自己相関を考慮した多シンボル遅延検波}, year = {2000} }
