Diversity gain's influence on MIMO's detection

Abstract

Multiple-input and multiple-output (MIMO) is a promising technology that realizes the enormous capacity in future wireless communication systems. For multi-stream detection there are many algorithms. In this paper, we investigate the diversity gain's influence on detection performance of these algorithms. Through three groups simulation with different diversity, we verify that the diversity changes the performance gap between different detection algorithms. The simple detection may be adopted with the same performance as the complicated detection in some practical systems.
