Abstract

A suboptimal iterative demodulation and decoding receiver is presented for an LDPC coded spatial multiplexing OFDMA system. The proposed receiver is based on spatial demultiplexing at the first iteration and the interference cancellation with soft decoding outputs at the following iterations. It is shown that the proposed receiver can reduce the complexity of the optimal iterative demodulation and decoding with a slight performance degradation. Moreover, we can achieve a performance gain over the non-iterative receivers if more latency is acceptable at the receiver.
