| 摘 要： | 针对Turbo码编码中应用的RSC编码器盲识别问题,提出一种反向验证的方法,对其参数进行识别分析。通过对RSC编码器参数进行遍历估计,重新输入码字序列,将得到的码字序列与原来的输出序列进行对比,找出最优的参数组合,完成对RSC编码参数的识别。仿真实验表明,该方法能够有效完成对RSC编码器的参数识别,特别在误码率为0.3时,依然能够达到识别效果,具有较好的容错性能。

| Abstract: | In order to solve the problem of the blind recognition of RSC encoder on the Turbo coding,a method of reverse verification is proposed. By traversing the RSC encoder parameters estimation,re-entering the codeword sequence and comparing the obtained codeword sequence with the original output sequence,we can find the optimal combination of parameters and complete identification of the RSC encoding parameters. Simulation result showed that this method can effectively complete the RSC encoder parameter identification,and still be able to achieve recognition results in BER 0.3.It reflects a better fault tolerance. |
