The received signal y<SUB>0</SUB>(t) is modulated by M-ary-QAM method. The same signal is received by the receiver 0 and receiver 1 through different paths. First, the receiver 0 detects the received signal and calculates a posteriori probabilities for the detected signal. These a posteriori probabilities are sent to the receiver 1. The receiver 1 detects the same signal and calculates second a posteriori probabilities using the probabilities sent from the receiver 0. The second a posteriori probabilities are sent to the receiver 0 and used to calculate third a posteriori probabilities in the receiver 0. These processes are repeated several times. Finally, both a posteriori probabilities of the receiver 0 and 1 are combined to decide the received signals.
