摘要：
In this letter, we investigate the outage performance of two-way relaying system based on the fixed gain amplify-and-forward protocol and asymmetric traffic requirements. At first, we propose a three-step scheme to obtain the channel state information with a low-complexity relay. Then, the exact expression of system outage performance is derived and we further investigate the asymptotic performance at high signal-to-noise ratio. Finally, numerical results are given to verify the analytical results.
