Abstract :
In this paper, the joint effect of both imperfect channel state information (CSI) and co-channel interference (CCI) on the dual-hop two-way amplify-and-forward relaying system (AF TWRS) is investigated. Assuming a Nakagami-m fading environment, we firstly obtain the effective end-to-end signal-to-interference plus noise ratio (SINR) expressions and then derive the closed-form approximate expression for the overall outage probability. Monte Carlo simulations verify the tightness of our approximation with the exact outage probability.
