摘要
根据线性分组码相关特性和矩阵分析的原理,提出一种对数字通信系统中交织进行检测的方法.首先建立了交织检测识别模型,通过求解矩阵标准形的秩分析其是否随矩阵维数增大而成比例增大,从而判定有无交织器,实现交织的检测.仿真结果表明,该检测方法在误码率不大于10-3时,能达到100％的识别概率,具有较高的容错性能.
Abstract
The paper proposes a method for interleaver detection based on the correlation characteristic of linear block codes and matrix analysis.In the detection,the recognition model is established first,and the rank of matrix standard form is calculated.The interleaver then can be detected by judging whether the rank changed with the dimensions of matrix.Finally,the simulation results shows that the proposed method is highly robust to the bit errors,and almost 100％ identification probability can be obtained for the bit error rate (BER) lower than 10-3.
