中文摘要：

针对高速无线通信中的多径干扰问题,对比分析了解决该问题的OFDM技术和SC-FDE技术的区别和联系,给出了MIMO-SC-FDE系统模型。将Nakagami-m衰落分布引入该系统,通过调整衰落指数m来模拟不同信道环境下的系统性能。仿真表明,随着衰落指数的增加,系统误码率迅速升高,同时信道容量随之减小;当信噪比较低,衰落指数大于等于4时,系统误码率将无法满足通信需求。根据仿真结果,减小衰落指数的同时适当增加信噪比有利于系统性能的提升。

英文摘要：

As to the problem of interferences in multi-channels in high data communication,the article has analyzed differences and affiliations of the technologies,including multi-carriers in orthogonal frequency division multiplexing and single-carrier frequency domain equalization,to conquer it contrastively.It has put through the system model of multiple inputs multiple outputs-single carrier frequency domain equalization.It has also brought forth the Nakagami-m distributing to the system to simulate different fad...
