摘要 预编码技术是多入多出(M IMO)系统的关键技术之一。在获得发射端信道状态信息(CSIT)的条件下,预编码器对信号进行一定的处理,以简化接收端设计或提高系统性能。文章介绍了预编码器设计的起源、原理及当前的各类预编码器设计方案,指出了预编码技术尚待研究的问题。 Precoding is one of the key techniques of multiple-input-multiple-output systems. Given the channel state information at the transmitter ( CSIT), the precoder processes the signal so as to simplify the receiver design and to improve the system performance. The origin, principle and vari- ous algorithms of precoder designs are described. Further, the open problems of precoding are proposed.
