多接收子阵下特征波束的角度空间调制方法
Angle Space Modulation Method for Eigen Beams with Multiple Receiving Subarrays
摘要
Abstract
Based on beamforming beam switching spatial modulation algorithm,it can improve spectrum efficiency,and it also can use antenna array gain to enhance energy efficiency.In this paper,a statistical average covariance matrix is constructed by using channel response,and the orthogonal feature vectors are constructed as weighted vectors for array.It forms multiple independent equivalent transmission channels,utilizing beamforming gain and diversity gain to improve the transmission reliability and capacity of wireless communication.Furthermore,an antenna subarray grouping method is proposed to overcome the adverse effects of channel correlation.Both performance analysis and simulation results indicate that the feature beam angle spatial modulation scheme can obtain more beam combinations,significantly improve decoding performance and spectrum efficiency.关键词
