碩士 === 國立暨南國際大學 === 電機工程學系 === 100 === In wireless networks, cooperative relaying is an emerging technique that provides spatial diversity in an alternative way. The overall system capacity of cooperative communications can be improved by the help of relay stations. The single antenna user nodes at the transmitters and at the receivers share their antennas to form a virtual multiple antenna system and to realize the cooperative communication diversity. It can enlarge the system’s capacity and enhance the service quality of the ad hoc network and improve the system’s performance. Applying the orthogonal property of the space-time coding, and we provide the single symbol decoding methods for the situations in decode and forward (DF) mode and amplify and forward (AF) mode separately. Lest, we jointly Adaptive Power Adjusting went to find the optimization solution for the optimization problem , we can enhance the system’s performance.
