摘　　要：为改善大规模毫米波多输入多输出的性能,提出一种基于目标分解的逐次迭代逼近混合预编码算法。基于目标分解,通过采用逐次迭代逼近、交替优化的求解方法和加入中继设备扩大传输范围的模型设计方法,研究混合预编码矩阵设计的问题。仿真结果表明,所提算法可以获得更加理想的系统均方误差和总和速率,其性能逼近理想预编码性能,具有有效性和可靠性。To improve the performance of large-scale millimeter wave multiple-input multiple-output,a successive iterative approximation hybrid precoding algorithm based on target decomposition was proposed.The algorithm was based on target decomposition.The problem of hybrid precoding matrix design was studied by adopting successive iterative approximation,alternate optimization and model design method to expand the transmission range by adding relay equipment.The simulation results show that the proposed algorithm can obtain more ideal system mean square error and achievable rate,and its performance is close to the ideal precoding performance.It can be seen that the algorithm has good effectiveness and reliability.
