Abstract :
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.
