An EM-Based Forward-Backward Kalman Filter for the Estimation of Time-Variant Channels in OFDM
Orthogonal frequency division multiplexing (OFDM) combines the advantages of high achievable rates and relatively easy implementation. However, for proper recovery of the input, the OFDM receiver needs accurate channel information. In this paper, we propose an expectation-maximization algorithm for...
