Blind identification method for coding parameters of extended Golay code of error-tolerant code

Abstract

The invention discloses a blind identification method for coding parameters of an extended Golay code of an error-tolerant code, and relates to the technology of intelligent communication, communication reconnaissance, and information security in the field of communications. By adopting the characteristics that the extended Golay code only has even code weight and an inner product of an encoding sequence and a check matrix is zero, the blind identification of the encoding parameters of the binary extended Golay code is realized through the communication contents only, and the aims of intelligent communication and communication reconnaissance are fulfilled. The blind identification method has the characteristics of simple algorithm, robustness of performance, high identification speed, high precision and the like, and is particularly suitable for channel encoding identification algorithm in the fields of intelligent communication, communication reconnaissance, radio detection, communication countermeasure, and the like.

Description

technical field [0001] The invention relates to an error-tolerant extended Golay code encoding parameter blind identification method in the communication field, and is particularly suitable for channel encoding identification algorithms in the fields of intelligent communication, communication reconnaissance, radio detection, communication confrontation and the like. Background technique [0002] At present, due to factors such as channel and time delay in intelligent communication, information may not arrive in real time and accurately, and sometimes it is necessary to change the coding system according to changes in the environment and time. In this communication environment, it is impossible to achieve synchronous communication through protocols, so Rapid identification of coding schemes is required. In the field of information interception, channel coding parameters are identified according to the intercepted data to obtain more original information, which provides a rel...
