Abstract :
In the communication systems using OFDM, it is necessary to compensate the influence of frequency selective fading caused by multi-path. In this paper we propose a MAP data reconstruction from the data symbols spread in the frequency domain in OFDM transmission. The performance of the proposed scheme is examined by computer simulation and good performance is confirmed.
