Combined channel information acquisition and beam forming method

The invention belongs to the technical field of wireless communication, and particularly relates to a combined channel information acquisition and beam forming method. The invention provides a combined channel information acquisition and beam forming design scheme based on a codebook and redundant dictionary orthogonal matching pursuit (CB-ROMP). Firstly, a codebook is designed based on the thought of minimizing total coherence, a collaborative design problem of an HBF is decoupled into two sub-optimization problems of a sending end beam forming factor and a receiving end combination factor which are relatively independent, and a universal beam forming codebook design is given. Based on the codebook, a redundant dictionary-based orthogonal matching pursuit (ROMP) algorithm that can increase angular resolution is then used to acquire channel information. 本发明属于无线通信技术领域，具体涉及一种联合信道信息获取和波束赋形方法。本发明提出了一种基于码本和冗余字典正交匹配追踪(CB-ROMP)的联合信道信息获取和波束赋形设计方案。首先基于最小化总相干性的思想设计码本，将HBF的协同设计问题解耦为相对独立的发送端波束赋形因子和接收端组合因子两个子优化问题，给出一种通用的波
