摘　　要：为实现变换域通信系统(TDCS)与多输入多输出技术(MIMO)的优势互补,将两者结合,使系统的数据传输速率和抗干扰性能得到进一步的提升。在对TDCS和MIMO理论研究和前人研究的基础上,细化了MIMO-TDCS系统收发机结构模型,详细分析了系统抗干扰原理,仿真了系统受到单音干扰、多音干扰以及窄带干扰时系统的误码率性能。实验结果表明,MIMO-TDCS是一种可靠的抗干扰通信系统。To make the advantage inosculate reasonably,TDCS and MIMO are combined,so that bit rate and anti-jamming performance are enhanced effectively.Based on the research of TDCS and MIMO and the study of formers,transmitter/receiver model are refined,and anti-jarnming theory is analyzed as well.Finally,the anti-jamming principle is simulated under single-tone jamming,multi-tone jamming and narrowband interference.It shows that MIMO-TDCS is a kind of reliable communication technique which has strong anti-jamming ability.
