A simple channel simulator for multiuser MIMO broadcast channel systems

Abstract

This paper presents an effort to construct a multiuser (MU) multiple-input multiple- output (MIMO) broadcast channel (BC) model.Our method is able to adequately build in the correlation and mutual coupling, which are important factors affecting the multi-antenna arrays.This helps to decrease the need for complex mathematical analysis and allows an easy simulation of the MU MIMO BC performance.The characterizations of MU MIMO systems are done and the impact of varying the number of transmitting and receiving antennas is explored.These insights are useful in physical realization of the systems.
