Blind recognition of channel coding plays an important role in the field of non -cooperative signal processing,which has been extended from the signal level to the information level.Blind recognition of channel coding is widely used in the fields of intelligence communication,information interception and information c ountermeasure.Firstly,the recognition algorithms of convolution code,BCH code,RS code,Turbo code and scramble code which are commonly used in modern digital com munication systems were summarized and classified.Then the theories of the algor ithms were described,and the computational complexity and performances in noisy environment of the algorithms were analyzed.Finally,the future of blind recognit ion of channel coding was pointed out based on the shortcoming of current algori thms and practical need. |
