OFDM modulation combines the advantages of high achievable rat-and relatively essy implementation. However, for proper rec.overy of the input, the receiver needs accurate channel information. In this paper, we propose an expectation-maximiaai~~ (EM) algorithm far joint channel and data recovery. The algorithm makes use of the rich structure of the underlying communiCation problem-a structure induced by the data and channel constraints. These constraints include pilots, the cyclic prefix (CP… CONTINUE READING
