The Test Platform Of Blind Decoding Algorithm For Convolutional Codes In Non-Cooperative Channels

The blind recognition of channel encoding technology refers to fast and effective analysis of coding methods and parameters based only on the limited intercepted coding data.The technology has very important practical value in the military field and in the field of information confrontation.The main research question of this paper is the blind recognit ion of convolutional codes in non-cooperative channel,the research status of the blind recognit ion algorithms of convolut ional codes has been summarized,the existing common blind recognition algorithms of convolut ional codes have been simulated,the recognition effect of the exist ing common blind recognition algorithms have been compared to each other,the bit-error-rate(BER)sensitivity of these algorithms have been analyzed.In this paper,we have outlined that the linear matrix analys is method has a good effect on basic parameters of convolut ional codes with error,the W-H method has a high anti-error capability in the matrix generation procedure of convolutional codes recognit ion.Furthermore,through the combination of the linear matrix analysis method and the W-H method,a testing platform of the blind decoding of convolutional codes has been buit up in this paper.Thus,on this basis,to complete the recognit ion of output parameters of convolut ional codes,one can realize the blind decoding of convolutional codes.
