An important special case (with many applications in communications) is the conversion of "soft-bit" messages to Gaussian messages. By this method, the performance of a Kalman equalizer is improved, both for uncoded and coded transmission.Proc. of the 44th Allerton Conference on Communication, Control, and Computing, Monticello, Ill., USA, Sept. 2006Information Theorytext
