Performance analysis of distributed MIMO with ZF receivers over gamma shadowed correlated Rician fading channels

摘要: Abstract In this paper, we study the performance of distributed multiple-input multiple-output (D-MIMO) systems over correlated Rician/Gamma (RG) fading channels employing zero-forcing (ZF) receivers. Contrary to existing works, consider arbitrary-rank deterministic Rician multipath and Gamma shadowing fading. Based on model, novel analytical expressions for achievable sum rate (ASR), symbol error ratio (SER), outage probability (OP) are derived, followed by asymptotic at both high- low- signal-to-noise (SNR) regimes. However, final results involve special functions like Bessel, Meijer-G functions, which do not provide engineering insights practical systems. To solve problem, approximate analyses ASR, SER, OP executed using moment matching method. Finally, perform large-system analysis ASR when number antennas base station (BS) grows large, ends large with a fixed finite ratio. It is demonstrated that proposed accurately match expressions, especially massive MIMO
