This paper proposes two new types of maximum a posteriori probability (MAP) receivers for multiple-input–multiple-output and orthogonal frequency-division multiplexing mobile communications with a channel coding such as the low-density parity-check code. One proposed receiver employs the expectation-maximization algorithm so as to improve performance of(More)
AbsfracrThis paper proposes a new Maximum Likelihood OFDM receiver for multipath fading environment with large delay spread The large delay difference over the Guard Interval (GI) duration of the OFDM signal generally results in Inter-Symbol Interference (ISI) between temporally adjacent symbols and Inter-Channel Interference (ICI). Both of them spread over(More)
