摘要

In this paper, we propose a novel blind iterative channel estimation algorithm for the Orthogonal frequency division multiplexing (OFDM) communication system, where pilot symbols for estimating multipath channel are no longer needed. Since channel coding can introduce sufficient coding gain to enhance the robustness of communication systems, we iteratively feed the hard-decision bit information ou...
