ABSTRACT:
Transmitted symbols are estimated from received signals. The likelihood of the estimated transmitted symbols is calculated. The mean value and variance of the transmitted symbols are calculated from information indicating the likelihood, and MMSE coefficient for compensating the channel is calculated according to the mean value and variance. The transmitted symbols are estimated again using the MMSE coefficient. The estimation process is repeatedly performed twice or more.
