Construction method of channel information quantization codebook in multi-antenna system and device thereof

多天线系统中信道信息量化码本的构造方法及装置

Abstract

本发明公开了一种多天线系统的信道信息量化码本的构造方法及装置,根据信道的相关特性、发送端和接收端的天线极化特性,构造信道矩阵的秩为1和2的信道码字,形成信道信息量化码本,所述信道信息量化码本包括与双极化匹配的信道矩阵的秩为1和2的信道码字。所述信道码字包括相关信道码字和/或不相关信道码字。应用本发明,可构造出满足双极化信道的信道信息反馈要求的量化码本,在多天线系统中对双极化天线的信道获得良好的匹配信道特性。
The invention discloses a construction method of a channel information quantization codebook in a multi-antenna system and a device thereof. In the invention, channel code words of which the ranks of a channel matrix are 1 and 2 are established according to relevant properties of a channel and antenna polarization properties of a sending end and a receiving end to form the channel information quantization codebook, wherein, the channel information quantization codebook comprises the channel code words of which the ranks of the channel matrix are 1 and 2 and which are matched with dual polarization; and the channel code words comprise relevant channel code words and/or irrelevant channel code words. By adopting the invention, the quantization codebook meeting the dual-polarized channel information feedback requirement can be established, and good channel matching characteristic can be obtained for the channel of dual-polarized antenna in the multi-antenna system.
