Abstract
In this paper, We proposed an iterative method to estimate the instantaneous probability of error (IPE) and carry maximum likelihood (ML) detection for differential decode-and-forward (DDF) transmission scheme of two-user cooperative communication system. With this method, the transmission of source-to-relay SNR from relay to destination, which is necessary in the previous scheme [4], is not required. The bit error rate (BER) performance is better than previous scheme [4] which is based on average probability of error (APE)[3].
