基于迭代列消元法的线性分组码参数盲识别
Blind Recognition of Linear Block Code Parameters Based on Iterative Column Elimination Algorithm
摘要
Abstract
To improve the fault tolerance performance of blind identification of linear block code parame―ters,an iterative column elimination algorithm is proposed. First,the iterative column elimination algorithm is applied in the intercept matrix,and then the corresponding column in the transition matrix of a dependent column is placed in candidate parity-check matrix. In addition,the codeword length and synchronization are estimated when the normalized dual space dimension reaches the maximum. Finally,check matrix is es―timated through elementary row transformation of dual code. The simulation results show that compared with previous blind identification method,the proposed method has good fault tolerance,and can recognize codeword length,synchronization and generator polynomial for linear block codes with different rate.关键词
