Problems solved by technology

[0009] The problem solved by the present invention is that in the prior art, the end part that marks the end of the data body and the data body conform to a common encoding rule, so that the receiving end cannot correctly detect the end bit of the data body, thereby making the length of the data body wrong, Affect the decoding effect and cannot restore the original information

Embodiment Construction

[0033] The present invention uses the broken bit that violates the coding rules to represent the end of the data sequence, so that in the process of detecting the data sequence, it can detect the violation of the code according to the detected state changes between adjacent symbols. The damaged bits of the above encoding rules are correctly extracted from the data main body in the data sequence, and the information of the data sequence is correctly restored accordingly. Before describing the detection method of the data sequence and recovering information from the data sequence of the present invention, a brief description of the data sequence is first required.

[0034] In this embodiment, the data sequence is described by taking the frame structure as an example, including a leading part, a data body and an ending part, wherein the data body is coded information that encodes information according to a coding rule, and The leading part and the ending part are additional ident...

Abstract

A detection method of data sequence comprises the following steps: when the data sequence is received, detection is carried out on each code element of the data sequence to obtain the changes of states between adjacent code elements; according to the changes of states between adjacent code elements, the code elements violating the coding rule are detected, and the code elements are destruction bits used for representing the end of the data subject; compared with the prior art, the invention has simple detection method by detecting the data sequence with destruction bits, can improve the correctness for detecting the lengths of data, and is beneficial for decoding and recovering the original information of the data sequence. The invention further provides a method for recovering information from the data sequence.

Description

technical field [0001] The invention relates to a data sequence detection method and a method for recovering information from the data sequence. Background technique [0002] In a typical communication system, information is sent from a sender in the form of a communication signal, transmitted through a transmission medium, and received by a receiver. However, general communication signals will inevitably introduce some interference such as noise, delay or distortion during transmission in the transmission medium. When the receiving end receives the part of the affected communication signal and restores it to the original information, the interference It will cause judgment errors, the original information cannot be restored or the restored original information is partially wrong. Therefore, in order to enhance the anti-interference performance of the communication signal, the communication signal to be transmitted will be encoded at the sending end, and then the communicat...
