Abstract: The adaptive AF relay combined with the active antenna system (AAS) and angle estimation strategy is studied in this paper. To improve the system performance, we introduce the AAS scheme into AF relay. Meanwhile, we also propose a joint AAS relay (JAR) angle estimation strategy to obtain the useful horizontal angle information. Results show that, in the temporary cover or emergency communication scene, the adaptive AF relay with AAS helps to improve the system performance gain effectively and also enhance the robustness stably.
