Abstract

Unified average sum-bit error rate (BER) analysis is carried out for amplify-and-forward (AF) two-way relay networks with direct links in Rayleigh fading. Average combined sum-BER bounds are provided in closed-form with a simple expression for different protocols including a novel one using four time slots. High signal-to-noise ratio (SNR) performance is also presented for its simplicity. Finally, all performance is compared using simulations, and it can be seen that the proposed protocol with normalized rate and power outperforms other protocols when average transmit powers from two sources are sufficiently different.
