摘要：We propose a pre-coded OFDM iterative detection scheme. The proposed scheme recovers the pre-coded data symbols that 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 then detected again using the recovered pre-coded data symbols.We confirmed by numerical analysis that better performance under severe frequency-selective fading channels can be achieved by iteratively repeating the proposed scheme.
