Signal decoding method based on Manchester encoding rule

The invention discloses a Manchester encoding rule-based signal decoding method, and provides a Manchester signal decoding method according to the characteristics of a signal output by a Manchester receiving circuit, which comprises the following steps of: firstly processing burrs, and then decoding by adopting joint judgment of a front effective high level and a rear effective low level to increase the decoding stability; therefore, decoding can be correctly carried out when phenomena such as jump point offset and signal burrs occur in Manchester signals in practical application, an original bit data sequence can be recovered, and the decoding correctness can be improved through the mode. 本发明公开了一种基于曼彻斯特编码规则的信号的解码方法，根据曼彻斯特接收电路输出的信号特点，提出了一种曼彻斯特信号解码的方法，首先对毛刺进行处理，然后采用前后两个有效高低电平联合判决进行解码，增加解码的稳固性，使得在实际应用中曼彻斯特信号出现的跳变点偏移和信号毛刺等现象时也能正确进行解码，恢复出原始比特数据序列，通过上述方式可以提高解码的正确性。
