Asymptotic Analysis of Rayleigh Product Channels: A Free Probability Approach
IEEE Transactions on Information Theory(2017)
摘要
The Rayleigh product channel model is useful in capturing the performance degradation due to rank deficiency of MIMO channels. In this paper, such a performance degradation is investigated via the distribution of mutual information assuming the block fading channels and the uniform power transmission scheme. Using techniques of free probability theory, the asymptotic variance of mutual information...
