Abstract
We propose an improved Joint Spatial Division and Multiplexing (JSDM) method which can be applied under the SCM model. The performance of basic JSDM under the SCM model is analyzed, and the problem of overlapping scattering angles is solved by adopting beamforming at user terminals (UTs). Simulations show that the idea of JSDM can be transplanted to the SCM model and the proposed method can greatly reduce the overhead of downlink training and uplink feedback for CSIT acquisition.
