【Abstract】 A novel method for blind recognition of punctured convolutional codes with rate of(n-1)/n is proposed.The property of linearity and parity check are taken into account in the method.By forming and solving the linear equation set in the dual domain with an optimum way,the problem of estimating the polynomial parity check matrix is solved.Then the source polynomial generator matrix and puncturing pattern is estimated by means of polynomial parity check matrix based on the mathematic transformation model of punctured convolutional codes.更多还原
