In order to solve the problem of the blind recognition of Turbo codes,some methods for blind recognition of the Turbo coding parameter with trellis termination are proposed for the first time. Based on the analysis of the sub-encoder structure of Turbo codes,some analytical models of convolutional codes at a rate of 1/2 are proposed, and by recoverying the interleaver sequence of Turbo codes,interleaver mapping is decided by exhaust comparison, and blind recognition of Turbo codes with trellis termination is realized.Simulation results illustrate that given the unknown Turbo encoded data sequence, the recognized coding parameters are correct by comparing prior conditions which validates the accuracy of the proposed methods.

Key words: channel coding, Turbo codes, convolutional codes, blind recognition
