Performance analysis of distributed MIMO systems in Rayleigh/Inverse- Gaussian fading channels
Paper i proceeding, 2012

In this paper, we pursue a performance evaluation of distributed multiple-input multiple-output (MIMO) systems in composite Rayleigh/Inverse- Gaussian fading channels. Capitalizing on some generic bounding techniques, we first derive new closed-form bounds on the ergodic capacity of optimal receivers. In order to gain useful insights into the impact of fading parameters on optimal receivers' performance, a detailed characterization in the asymptotically high and low signal-to-noise ratio regimes is also provided. In addition, we explore the 'large-system' regime and provide asymptotic expressions when the number of antennas grows large. A similar performance analysis is performed for the achievable sum rate of distributed MIMO systems employing linear minimum mean-square error receivers.
