摘　　要：在对MIMO-OFDM(Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing)模型分析的基础上,对MIMO-OFDM系统中常见的干扰信号进行了深入研究。通过仿真分析比较了采用不同空时编码的基础上MIMO-OFDM系统对不同干扰信号的抗干扰性能。仿真结果表明:处于小区边缘的用户受到干扰信号的影响比较严重,并且与实际的MIMO-OFDM应用系统的联系比较紧密;相对于采用BLAST编码方式的MIMO-OFDM系统采用STC编码方式的MIMO-OFDM系统具有更好的抗干扰性能。Based on model analysis of Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing,the common interference of MIMO-OFDM system is researched deeply. Through the simulation analysis,the difference anti-jamming performance of difference jamming signals from MIMO-OFDM system with different space-time code are compared. The result of simulation indicate that at the cell edge users affected by the interference signal is more serious,and connect closely with the practical application of MIMO-OFDM system; and the MIMO-OFDM system of STC coding method has better anti-jamming performance than MIMO-OFDM system adopts BLAST coding mode.
