摘要
Cooperative diversity obtains the spatial diversity gains created by sharing antennas of terminals in wireless networks. In this paper, adaptive amplify-and-forward (AF) cooperative diversity with multiple relays using phase feedback is introduced. Adaptive algorithm depending on channel condition and threshold obtained by computer simulation are introduced. Simple power allocation for proposed scheme is introduced. Adaptive AF cooperative diversity using phase feedback provides improved performance than the conventional AF cooperative diversity using phase feedback.
