摘要 MIMO技术利用多根天线实现多发多收,能够在不增加传输带宽和发射功率的条件下,成倍地提高系统的数据速率;而预编码技术则可以利用接收端反馈回来的信道状态信息对信号进行预处理以改善信号的传输性能,从而达到消除干扰的目的,使得无线通信系统的可靠性得以提升。因此对MIMO系统预编码技术的研究,是解决如何提升无线通信系统性能的关键问题,具有重大的研究意义。 MIMO technology, which realizes multiple input multiple output by using mutttple antennas, can improve the channel capacity efficiently and make it possible to transmit data under high speed without increasing spectrum resources and transmitting power of antennas. Pre-coding technology can pre- process signals so as to improve their transmitting performance by using the channel state information fed back from the receiver. Therefore it can eliminate the interference and improve reliability of wireless communication systems. As a result, the study on pre-coding technology of MIMO systems has great significance, which is a key solution to the problem that how to improve the performance of wireless communication systems.
