摘要

In this paper, a novel iterative soft joint detection algorithm for orthogonal frequency division multiplexing (OFDM) systems is proposed. Without the need of channel estimation, it directly generates the a posteriori probabilities (APPs) of data symbols by very efficient computation. With the increase of iterations, the proposed algorithm gradually achieves near-optimal performance, while its complexity is only linear in the number of subcarriers.
