碩士 === 國立中正大學 === 通訊工程研究所 === 101 === Cooperative communications are emerging wireless communications techniques recently. It plays an important role in new generation of wireless communications. For instance, Long Term Evolution–Advanced (LTE–Advanced) and WorldwideInteroperability for Microwave Access (WiMAX) as international standard of fourth-generation, which the relaying technology applies to. Network coding technology combines several messages at intermediate nodes and transmits the mixed message to destination nodes. Network coding could enhance throughput and improve transmission performance. In this thesis, we consider a cooperative communications system using one relay Enhance Static Decode-and-Forward (ESDF) protocol with network coding and one relay node. We research symbol error rate of this system with PSK and QAM modulation under Rayleigh and Nakagami fading channels. We analyze the variable of symbol error rate in different systems which have different transmission rates. The results show that our system has better symbol error rate which means the improvement of the reliability of system.
