摘　　要：为了提高无线通信系统的可靠性,采用极具纠错性能的Turbo乘积码与空时分组码级联,构成Turbo乘积码编码的MIMO-OFDM系统。测试了采用三种Turbo乘积码的两发两收MIMO-OFDM系统在通过IMT2000信道后的性能。仿真结果表明采用Turbo乘积码后的MIMO-OFDM系统性能有明显改善。The Turbo product code（TPC） coded MIMO-OFDM system was proposed to improve the reliability of the wireless communication systems. In the proposed system, TPC with excellent error-correction performance was concatenated with space time block code（STBC）.The MIMO-OFDM system with two transmit antennas and two receive antennas was tested over IMT-2000 channels, in which three types of TPC were used. The simulation results show that MIMO-OFDM system performance based on TPC is evidently improved.
