On the Asymptotic Analysis of Mutual Information of MIMO Rician Correlated Channels
The analysis of mutual information and capacity of block fading MIMO static channels has generated considerable interest since the seminal work of Telatar in 1995. The vast majority of these works have addressed the case of Rayleigh MIMO channels. Despite its importance, the context of Rician MIMO channels seems to have been studied much less extensively. The authors however mention. In particular, important problems such as the study of the impact of the statistical properties of the channel on the mutual information and the capacity, or the derivation of reliable algorithms for finding the optimum input covariance matrix achieving the ergodic capacity of general correlated Rician channels have not yet been solved completely.
