碩士 === 國立臺灣海洋大學 === 通訊與導航工程學系 === 99 === Adaptive Transmission System can use Performance Control Unit to Switch transmission states by different channel conditions. We can get good transmission performance when the SNR of channel is nice. When the channel condition is poor, the system can maintain average transmission quality. In this thesis, we have proposed a communication system with the adaptive cooperative communication system method.We can use Relay station to detect the channel condition. Source station may adjust coding and modulation method with the channel condition information provided by Relay station. System performance simulation has shown a better bandwidth efficiency.
