摘要

摘要本文介绍了费舍尔-斯内德科尔（F）衰减模型在干扰受限系统中采用选择组合（SC）分集方案的性能。推导了单用户干扰下无 SC 分集情况下的概率密度函数（PDF）和累积分布函数（CDF）。随后，计算了 SC 分集的 CDF 和 PDF 表达式。并给出了不同期望和干扰多径衰落参数下的 PDF。结果还说明了独立但不一定相同分布（INID）和独立相同分布（IID）变量的中断概率（OP）。分集分支数量越多，OP 性能越好。

Selection Combining Diversity for Fisher-Snedecor Composite Fading Model under Interference

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.
