Abstract

In this paper, we study joint dual relay- selection (RS) and physical network coding (PNC) schemes for wireless two-way relay channels. We propose four schemes in which the sources transmit information to the relays and two “best” relays are selected based on minimum bit-error-rate (BER) criterion. Then, the selected relays combine the received information from sources and broadcast it towards each other. The BER of the proposed schemes are obtained analytically and also verified through Monte Carlo simulations. The results indicate that the schemes have superior performance compared to an existing work which uses Alamouti space-time block codes (STBC).
