Abstract :
In this paper, we study the performance of relay selection in a two-way relay network (TWRN) using analog network coding (ANC) with asymmetric traffic requirements at the end terminals under imperfect channel state information (CSI). We derive the system outage probability under Rayleigh flat-fading channels with channel estimation error. Three different power allocation schemes are presented. Simulations validate our analysis and show the performance gain of the proposed schemes.
