Abstract
In this paper, the performance of dual selection combining (SC) receiver in communications systems with a Rician desired signal affected by multiple Nakagami-m cochannel interferences (CCIs) is studied. This investigation is important since such environment seems to be the most realistic in microcellular radio communications systems. The performance analysis includes the channel correlation effect since in practice diversity is usually applied in small terminals so antenna elements can not be placed sufficiently apart to achieve independent fading channels. With assumption that CCIs are mutually independent and identically distributed, analytical expressions for the probability density function (PDF) and cumulative distribution function (CDF) of dual SC output signal-to-interference ratio (SIR) are derived and used to investigate important system performance measures, such as the average bit error probability (ABEP), channel capacity and outage probability. The proposed mathematical analysis is complemented by various graphically presented numerical results to show the effects of various system's parameters. In addition, the impact of diversity to the microcellular system's performance is also explored. |
