Abstract

In this paper, we analyze the outage performance of relay-enhanced cellular systems in an interference-limited environment, where the co-channel interference (CCI) is a crucial factor that governs the overall system performance as compared to an AWGN (additive white Gaussian noise). Furthermore, the relay station and destination are subject to the different but arbitrary number of CCIs on each node. Assuming that the interference channels are statistically independent and nonidentically distributed (i.ni.d), we derive the outage probabilities for amplify-and-forward (AF) and decode-and-forward (DF) relay systems. We show that the statistics obtained from our analyses, e.g., probability density function (PDF) and cumulative density function (CDF), including the outage probability, closely coincide with simulation results.
