Abstract :
In this letter, we evaluate the outage performance of analog network coding (ANC) protocol for a two-way half-duplex relaying system with asymmetric traffic requirements at end terminals. We derive a simple and generalized expression for overall system outage probability in a Rayleigh flat-fading environment. We also deduce the optimal relay location and power allocation in order to minimize the overall system outage. Numerical and simulation results highlight the effect of optimal relay positioning and power allocation under various traffic requirements.
