Abstract

Relay network have received considerable attention, especially when limited size of terminals and power resources constraints in wireless sensor network. In this paper, we investigate the performance of two-way three-node amplify-and-forward relaying networks in the presence of channel estimation errors. Such problem is considered as the main cause of performance degradation in wireless communications. We analyze signal to noise ratio (SNR) under channel estimation error of two kinds of AF-based relaying networks. Finally, we simulate the outage probability in different manners for performance comparison.
