Performance Analysis of Cloud Radio Access Networks with Nakagami-m Fading Channel

Abstract

In this letter, the performance analysis of Cloud Radio Access Network (C-RAN) is investigated in terms of Ergodic Capacity (EC) under the well-known Nakagami-m fading channel. In this study, the C-RAN model is based on two nearest Remote Radio Head (2-RRH) association. The user is considered at the center of a disk equipped with a single antenna while each RRH has L antennas. The outage probability equation is defined and a closed form formula of EC has been derived with arbitrary path loss exponent. Numerical and analytical results show nonlinear behavior of channel capacity versus signal to noise ratio.
