Massive MIMO System Performance in Asymptotically Full-Diversity-Gain and Degeneration Regimes for Rayleigh Max/Min-semicorrelated Channel Models

Abstract

The proposed research presents an analysis of MIMO system performance for two models: max- and minsemicorrelated channels. Closed form analytical expressions for finite signal-to-noise ratio (SNR) diversity gain which is the practically valuable indicator of MIMO system reliability were derived. The values of SNR which put the system into asymptotically full-diversity-gain and degeneration regimes are obtained for both models. The influence of such factors as signal constellation size, MIMO system geometry, one-step correlation coefficient on the SNRs are described. The results demonstrate the achievable efficiency of the system in terms of diversity and hence reliability, and under what conditions it is achieved.
