An iterative detection of precoded OFDM under frequency selective fading channels

In this paper, an iterative detection scheme of precoded OFDM is proposed. The proposed scheme recovers the precoded data symbols correspond to the carriers whose reception powers are degraded by frequency selective fading by using the data symbols after decision and the data symbols are detected again using the recovered precoded data symbols. As the result of numerical analysis, it is confirmed that better performance under severe frequency selective fading channels can be achieved by iteratively repeating the proposed scheme
