摘　　要：从4种预编码码书的构造比较了它们的波束成形存储量和计算复杂度,在有限反馈自适应4发2收MIMO系统中仿真,比较了它们的误码率,结果显示:SNR=10 dB时,TI码本的误码性能较好,grassmanian码书的性能变差.The beam-forming storage and computational complexity of four kinds of pre-coding codebook construction are compared. The bit error rate of the limited feedback adaptive system which has four transmitting antenna and two receiving antenna is simulated. The results show that TI has the best performance and Grassmanian has the worst when SNR is 10 dB
