An Iterative QR-SIC Receiver for Concatenated Space Frequency Coding Schemes in Severe Multipath Channels
Abstract—This paper studies an efficient receiver design for concatenated space-frequency coded orthogonal frequency division multiplexing (OFDM) systems under severe multipath channels. The proposed receiver utilizes a Turbo-like iterative QR decomposition based successive interference cancellation (QR-SIC) algorithm that exploits both spatial and frequency diversity inherent in the multipath multiple-input multiple output (MIMO) channel. Performance of the proposed receiver is evaluated via Monte Carlo simulations. Our results show that the proposed iterative QR-SIC scheme attains excellent performance improvements in severe multipath fading channels. In addition, the proposed scheme attains manageable receiver complexity since we only consider a maximum of 2-3 iterations.
