In this work, we consider an amplify-and-forward two-way multi-relay system for wireless communication and investigate the effect of channel estimation error on the error rate performance. With the derivation of effective signal-to-noise ratio at the transceiver and its probability density function, we can get approximate expression for average bit error rate. Simulation results are performed to verify the analytical results.

Key words:

cooperative diversity, two-way multi-relay, Rayleigh fading channels, amplify-and-forward relaying, channel estimation error, error probability
