Low Computational Two-Stage Design of Multiuser MIMO System with Large Transmit Array

摘要

This study presents a low computational two-stage design method of multiuser MIMO system with large array antenna in transmitter side. In previously presented work which is based on subarray processing, the possible number of receivers is small compared with the maximum acceptable value. Therefore, to increase the user number, a two-stage design approach is considered. Some features of the proposed approach are verified through computer simulations.
