A Unified Description of Generator Matrix of Expansion Convolutional Codes
摘要
Abstract
In order to get enough priori knowledge about the expansion convolutional codes in the process of blind recognition of punctured convolutional codes,a method for describing the unified generator matrix of the mother code and the expansion convolutional codes is proposed. Through analyzing the basic physic principle of the relationship between the input and the output of encoding,the method first sets ( n,1,m) and( n,k,m) convolutional codes as the mother code,then constructs a correspondence coefficient model of the polymerization of the expansion convolutional coding,and finally introduces and proves a unified de-scription theorem about the generator matrix of the expansion convolutional codes. The verification shows that the theorem realizes the fast computation of the expansion generator matrix and is able to help to ex-haustively search and reconstruct the mother generator matrices and the puncturing patterns.关键词
