Performance Analysis of Amplify and Forward Cooperation Over Peak-Power Limited Channels

In this paper, the authors study the instantaneous power distributions of the transmitting signals at the relay in the non-regenerative and regenerative cooperation scenarios with linear modulation under the band-limited scenario. They study the following three relay function scenarios: fixed gain Amplify and Forward (AF) relay, variable gain AF relay, and Decode and Forward (DF) relay. Based on the analytical results, they reveal practical limitations of non-regenerative relays when the Power Amplifier (PA) efficiency is of primary concern.
