Wireless relay system with two sections in the presence of K-μ and η-μ multipath fading

摘要

Wireless communication relay radio system with two sections is described in this paper. In the first section, signal envelope is described with K-μ distribution and in the second section signal envelope is modeled by using η-μ distribution. Probability density function (PDF) and cumulative distribution function (CDF) of minimum of signal envelopes at sections are calculated. Then, the outage probabilities are calculated for two cases. In the first case, the outage probability is defined as probability when signal envelope falls below the predetermined threshold at any section, and the second case when the signal envelope at the output of relay system falls below the predetermined threshold. The influence of the Rician factor of K-μ distribution and parameter η of η-μ distribution on the outage probability is analyzed and discussed.
