摘　　要：根据纠错码的性质和卷积交织的特点,利用线性代数的相关知识提出了一种卷积交织器的检测方法。在识别出截获序列的相关长度和相关起始位的基础上,建立数据分析矩阵,通过分析数据矩阵的秩与列值的关系来判断截获序列是否经过卷积交织。仿真结果验证了该方法的有效性和较好的容错性。According to the property of the error-correcting codes and the characteristic of the convolutional interleaving,make the use of linear algebra to detect the convolutional interleaver.After get the related length and related initial state,we construct the data analysis matrix,and by compare the rank of the data analysis matrix with the column of the matrix,we can judge the intercepted sequence had a convolutional interleaver or not.The simulation result show the efficiently of the scheme and it also burst to the BER.
