中文摘要：
传统多输入多输出技术可以提高信道容量，但不能解决信号抗干扰问题；而变换域通信系统已经被证明是一种良好的抗干扰通信系统。通过引入变换域处理技术，提出了一种多输入多输出变换域通信系统（MIMO—TDCS），旨在突破传统MIMO系统的应用瓶颈。对其收发信机模型和抗干扰机制作了简要介绍，并通过仿真窄带干扰下的误码率性能，表明MIMO—TDCS是一种可靠的抗干扰通信手段。
英文摘要：
The conventional Multiple Input and Muhiple Output （MIMO）technology can improve the channel capacity, whereas the anti-interference ability is not so good. The Transform Domain Communication System （TDCS）has been proved to be a fine anti-interference communication system. Therefore, a MIMO-TDCS was proposed by integrating transform domain producing technology. The transmitter and receiver architecture of MIMO-TDCS were introduced, and the anti-interference principle was analyzed concisely. The simulation results show that MIMO-TDCS is a kind of reliable communication technique which has strong anti-interference ability.
