| 摘 要： | 针对归零Turbo码的识别问题,提出一种有效的识别方法。该方法首先根据归零Turbo码的特殊结构,利用遍历矩阵列数的方式,寻找相关列均值最大值的位置,识别归零Turbo码长和起始点;其次,构建归零Turbo码的交织器识别模型,利用分层比对的方法得到交织置换关系, 完成对交织器参数的识别。仿真实验表明,该方法在0.02的误码率条件下识别率仍能达到80%以上,验证了所提方法的有效性和鲁棒性。

| Abstract: | An effective method of recognition is proposed to solve the Turbo codes on the trellis termination problem. According to the special structure of Turbo codes on trellis termination, exhaustively search for the number of columns of the matrix to find related column average maximum, and complete recognition of the code length and the start point of Turbo codes on trellis termination. Then, build the interleaver model of Turbo codes on trellis termination, solve the interleaver parameter with the method of using the bitwise contrast based on hierarchy. Simulation results show that this method has better recognition results, which verify the validity and robustness of the method. |
