This paper provides an analytical framework for the outage probability evaluation of dual-hop decode-and-forward relay systems operating over κ-μ fading channels in the presence of co-channel interference.The interferers are independent non-identically distributed κ-μ fading.An accurate analytical-form expression for the cumulative distribution function of the received signal power to interference and noise ratio is derived.Various numerical results are compared with Monte Carlo simulation results in order to corroborate the accuracy of the proposed expressions.Our results show that increasing the value of kappa of main links will decrease the outage probability of relay systems.Furthermore,the system performance degrades with the number of interferences.

This paper provides an analytical framework for the outage probability evaluation of dual-hop decode-and-forward relay systems operating over κ-μ fading channels in the presence of co-channel interference. The interferers are independent non-identically distributed κ-μ fading . An accurate analytical-form expression for the cumulative distribution function of the received signal power to interference and noise ratio is derived. Various numerical results are compared with Monte Carlo simulation results in order to corroborate the accuracy of the proposed expressions. increasing the value of kappa of main links will decrease the outage probability of relay systems .Furthermore, the system performance degrades with the number of interferences.
