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.
