中文摘要：
该文针对60GHz通信网络上行链路提出一种基于码本的混合波束赋形技术，实现复杂度与接收性能之间的折中。用户设备采用固定码本波束切换发射信号，接收设备首先利用码本执行到达角预估，在此基础上进一步设计最佳接收波束，以抑制上行链路相互干扰；并设计一种改进的最小均方误差（LMS）波束形成算法，通过设置有效初值提升迭代性能。仿真结果表明，混合波束赋形算法可有效提升60GHz通信系统传输性能，同时验证新算法能显著提高接收信号的信干噪比。
英文摘要：
A hybrid beamforming technology for 60 GHz uplink communication system is proposed in order to compromise between performance and complexity. The beam-switching by a predefined beam codebook is applied at the transmitter, while DOA estimation based on the codebook and the optimum beamforming are used at the receiver. Meanwhile an improved Least Mean Square （LMS） algorithm is designed, which is able to increase the iterative performance effectively by providing the initial value. The simulation results show the hybrid beamforming algorithm, especially the improved LMS, can significantly enhance the SINR performance of receiver signal.
