In practical systems, limited feedback precoding based on codebook is used, due to the limited capacity of the feedback channel.

在实际系统中，由于反馈信道容量有限，采用的是基于码本的有限反馈预编码技术。

Because capacity of channel is limited by interference. Especially for the interference from the same channels and the adjacent channels.

由于信道的容量是由干扰所限定的，尤其是同信道干扰和邻信道干扰的影响更为严重。
