摘　　要：针对多入多出—正交频分复用(MIMO-OFDM)信号检测问题,基于并行干扰抵消技术提出了一种编码MIMO-OFDM系统联合检测与译码算法,通过在干扰抵消检测器和信道译码器之间传递判决信息提高系统的误比特率性能。计算机仿真表明,该算法获得的误码率性能较传统的迫零检测以及V-BLAST检测算法有了较大的提升。Aiming at multiple input multiple output-orthogonal frequency division multiplexing （ MIMO-OFDM） signal detection,a joint detection and channel decoding algorithm is proposed based on the parallel interference cancellation techniques.The BER perform-ance of the system is improved by exchanging the decision information between the channel decoder and PIC canceller. The computer simulation results show that the BER performance of this algorithm is better than the conventional MIMO detection algorithms,such as zero forcing algorithm and V-BLAST detection algorithm.
