文摘	信道编码盲识别是非合作信号处理领域的重要内容,将非合作信号处理技术从信号层扩展到了信息层,在智能通信、信息截获、信息对抗等领域具有重要作用.本文首先对广泛应用于现代数字通信系统中的卷积码、BCH码、RS码、Turbo码和扰码的盲识别算法进行了总结和归类,然后对算法原理进行了描述,并分别从计算量和误码适应能力两个方面对算法的性能进行了分析.最后,根据目前算法的不足和现实需求,指出了未来信道编码盲识别的研究方向.
其他语种文摘	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.
