Outage Analysis of Cognitive Spectrum Sharing for Two-Way Relaying Schemes with Opportunistic Relay Selection over i.n.i.d. Rayleigh Fading Channels

Abstract

In this letter, we analyze the outage performance of cognitive spectrum sharing in two-way relaying systems. We derive expressions of outage probability for the primary and secondary network over independent but not necessarily identically distributed (i.n.i.d.) Rayleigh fading channels. Monte Carlo simulations are presented to verify the theoretical analyses.
