【摘要】 针对信道编码的盲识别问题,首次提出了扩展Golay码的盲识别方法。与前有的盲识别算法比较,该算法的识别概率有明显的提高,这是一个全新的研究课题,在智能通信、信息截获、密码分析等领域有重要的应用。仿真实验表明文中提出的方法在误码率为8×10-2的情况下,对于扩展Golay码的识别概率高于99%,比原有算法提高了44%。更多还原

【Abstract】 In order to solve the problem of blind recognition of channel coding,the method of blind recognition of extended Golay code is proposed.Compared with the former blind recognition,the recognition probability has been obviously improved.This is a brand-new subject for research and has important application in such fields as adaptive communication,information interception and cryptanalysis.The simulation experiments show that the recognition probability for extended Golay code of the proposed method in the thesis is above 99%,enhanced by 44% compared with the original method at a bit error rate(BER) of 8×10-2.更多还原
