摘要
为了适应非合作条件下侦收码序列不完整这一特点，对已有1／2码率的卷积码盲识别多项式模型进行了修正。基于该模型，对经典欧几里得算法进行了改进，提出了一种基于改进欧几里得算法的1／2码率卷积码的盲识别算法，仿真结果验证了该算法的有效性。
The polynomial model of 1/2 rate convolution code blind recognition has been modified in order to fit the code sequence is not integrated in noncooperation communications. The classical Eu- clidean algorithm has been improved and a algorithm for blind recognition of 1/2 rate convolution code based on improved Euclidean algorithm is proposed. The validity of the algorithm is verified by the simulation results.
