Abstract :
This paper investigates the effects of antenna correlations on spatial diversity and multiuser diversity. Using an upper bound on achievable capacity from order statistic theory, we quantify the interactions between spatial correlation, spatial diversity and multiuser diversity. Our theoretical analysis and simulation results demonstrate a positive influence of spatial correlations on achievable capacity of spatial diversity techniques combined with multiuser diversity, while it has been known that spatial diversity limits a multiuser diversity gain without spatial correlation.
