Baud rate adjusting method and system

The invention is suitable for the field of baud rate adjustment, and provides a baud rate adjustment method and system, and the system comprises a signal sampling module, a data hypothesis module, a data candidate module, and a baud rate selection module. And different baud rate hypotheses are generated based on the features. The method can more accurately adapt to the actual communication environment. The Baud rate suitable for the actual communication situation is predicted and confirmed through the lookup table, the adjustment process is faster, higher accuracy is achieved, and the Baud rate selection method is more effective compared with the prior art. And the method can detect any mismatch of the start bit and the end bit of the data frame when the baud rate is set. Signal errors are reduced, it is ensured that data transmission is more correct, and high communication quality can be maintained under the unstable signal condition. 本发明适用于波特率调整领域，提供了一种波特率的调整方法及系统，所述系统包括：信号采样模块、数据假设模块、数据候选模块、波特率选取模块该方法利用现代信
