摘　　要：在无线通信系统中,信号衰落始终是影响整个通信系统整体性能的主要因素,而信道编码与协作通信均是有效对抗信号衰落的技术,将二者结合,更能进一步抵抗信号衰落。论文首先对循环Goppa码的构造原理进行了阐述,进而利用Goppa码与编码协作系统的特性,在此基础上提出了一种循环Goppa码编码协作系统的构造方案,在目的节点处将两路信号合并得到完整码长的Goppa码,这种联合迭代译码方案较好地改善了系统的误码率性能。最后利用Matlab对该系统做了性能仿真模拟,并对仿真结果进行了分析与比较,仿真结果表明,在AWGN信道和快衰落信道下,该系统性能都有不同程度的改善。In wireless communication system,signal fading is always the main factor affecting the overall performance of the whole communication system,and both channel coding and cooperative communication are effective techniques against signal fad⁃ing,and combining them can further resist signal fading.The paper firstly expounds the structure principle of cyclic Goppa code,then Goppa code and code collaboration system characteristics,on this basis,this paper proposes a cyclic Goppa coded scheme in the construction of the cooperative systems at the destination node will get full two-way signal merger code long Goppa code,the joint iterative decoding scheme better improve the ber performance of the system.Finally,Matlab is used to simulate the perfor⁃mance of the system,and the simulation results are analyzed and compared.The simulation results show that the performance of the system is improved in different degrees under AWGN channel and fast fading channel.
