Performance Analysis of Multiuser Two-Way AF Relaying Networks with Antenna Correlation

In this paper, we investigate the effect of spatial correlation on the performance of multiuser two-way amplify-and-forward (AF) relaying system. The lower bound of the sum rate are derived. Furthermore, the asymptotic expressions of the sum rate are analyzed when the number of mobile stations K is sufficiently large. Analysis and simulation results indicate that the achievable sum rates depend on the degree of spatial correlation and the number of mobile stations K. Especially, our results reveal the impact of the relay location with unbalanced hops on the sum rates.
