An Iterative Detection of Pre-Coded OFDM Combined with Convolutional Code

In this paper, an iterative detection scheme of pre-coded OFDM is proposed. The proposed scheme recovers the pre-coded 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 pre-coded 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 combined with convolutional error correcting code.
