摘　　要：为解决DF(decode-and-forward)无线通信系统中空频编码的问题,首先分析传统三中继空频编码SER(Symbol-error-rate),并得出SER的上界和闭合表达式,提出一种联合空频编码和网络编码的方法,分析其SER性能.研究结果表明:在DF系统中,联合网络与空频编码的方法比传统的空频编码具有更好的SER性能.In order to solve the problem of space-frequency coding, firstly, this paper analyzed the traditional symbol-error-rate(SER)in the decode-and-forward(DF)wireless communication system and concluded the upper bound and closed expression of SER based on this. Secondly, it proposed a joint space-frequency coding and network coding method. Thirdly, it analyzed SER performance. Lastly, the theory proves that in the DF system,the performance of joint network and space-frequency coding method is better than that of the traditional space-frequency coding.
