Asymptotic Performance of Bidirectional Dual-Hop Amplify-and-Forward Systems
This paper considers a bidirectional amplify-and-forward (AF) relaying system where two nodes communicate through an intermediate node due to the lack of a direct path. The communication is realized over Rayleigh fading channels in two phases: multiple access and broadcast phase. We derive closed form and asymptotic expressions for the outage probability of two-way wireless relaying system. The validity of our performance analysis for moderate and high signal-to-noise ratio (SNR) is verified with Monte Carlo simulations.
