Outage probability of two-way full-duplex amplify-forward relay systems with asymmetric traffic requirements

In this paper, we investigate the outage probability performance of a two-way full-duplex (TWFD) amplify-forward (AF) relay cooperative communication system in the presence of residual self-interference(RSI) at the source/destination terminals and relay node. We first give the closed-form expressions of the link outage probability under asymmetrical cases, in which the targeted data transmission rates in the bidirectional links are different. Based on the analytical expressions, we further analytically derive the exact expressions of the system outage probability with asymmetric traffic requirements. Besides, numerical results with the Monte Carlo simulations are also provided to verify the validity of our theoretical analysis.
