Abstract

The performance of the Fisher-Snedecor (F) fading model with selection combining (SC) diversity scheme over the interference-limited system is presented in this paper. The probability density function (PDF) and cumulative distribution function (CDF) are derived without SC diversity under single-user interference. After that, the expressions of CDF and PDF for SC diversity are computed. The PDF is presented for different desired and interferer multipath fading parameters. The results are also illustrated in terms of outage probability (OP) for independent but not necessarily identically distributed (INID) and independent identically distributed (IID) variates. The higher number of diversity branches shows better OP performance.
