A Low Complexity Channel Matrix Estimation Method for High Frequency System
Millimeter-wave/Terahertz communication is an important 6G candidate technology with high potential and impact factor,which supporting large operating bandwidth and ultra-high communication rate.A high-frequency communication channel estima-tion method for a hybrid beamforming architecture is proposed,which can effectively estimate channel information and have no require-ment for channel reciprocity.The proposed channel matrix estimation algorithm is implemented via matrix multiplication operation by constructing a special weight vector matrix,which avoid statistical covariance matrix inversion or eigendecomposition operation,and greatly reduce the implementation complexity and computing burden.
