Performance Analysis of Amplify-and-Forward Cooperative Communication Systems with Channel Estimation Errors over Nakagami-m Channels
Lei Wang, Yueming Cai, Junquan Hu, Weiwei Yang · 2011
We analyze the impact of channel estimation errors on amplify-and-forward (AF) cooperative communication systems over Nakagami-m fading channels. We derive exact closed-form expression of the average symbol error rate (SER) with channel estimation errors by using the moment-generating function (MGF) based approach. Numerical results confirm that our theoretical analysis is very accurate.
