摘要 提出一种基于两级码本结构的有限反馈自适应MIMO波束成形技术,对该两级码本进行一定的组合,得到一个码本集并从中选择用来量化的码本。在反馈码字索引的同时包含了码本选择的信息,从而实现码本的自适应切换。仿真结果表明,在相同误码率情况下,该方法能够降低反馈速率。 A two grade codebook based limited feedback beamforming system is proposed. The two codebooks are codebooks. And from the set, the codebook is chosen for tion information is also included in the feedback of codewor multi-input multi-output （MIMO） combined together to make a set of quantification. The codebook selecd index, thus realizing the eodebook adaptive switch. Simulation results show that the method can reduce the feedback rate at the same BER.
