Extended Asymptotic Outage Probability Analysis of Decode-and-Forward Cognitive Dual-Hop Systems With the Interference Constraint over Nakagami-m Fading Channels

Abstract

In this letter, we extend the analysis of outage probability of decode-and-forward dual-hop system over Nakagami-m fading to include non-integer fading parameters, which addresses a limitation of previous studies that were restricted to integer values. By deriving a generalized expression, we can provide a unified framework applicable to more general and practical scenarios. Extensive numerical results are presented to validate that our proposed closed-form formula can embrace more general Nakagami-m fading environments, obviously showing its compactness and accuracy.
