AI Technical Summary

Technical Problem

In existing technologies, the specifications of shortwave protocol sample data are not standardized and the amount of data is unbalanced, which makes training difficult and the efficiency of extracting burst signals is low, affecting the training effect of the shortwave protocol recognition model.

Method used

Burst signals are captured using an anti-fading energy detection method, down-converted to I/Q signals, and redundant information is filtered out using a low-pass filter. The signal amplitude and phase are calculated to form training data, which is then used for model training through a data augmentation and parameter configuration training device.

Benefits of technology

It improves the availability of real-world shortwave protocol samples, solves the problems of non-standard data specifications and unbalanced data volume, and enhances the training efficiency and accuracy of the shortwave protocol recognition model.

Abstract

The application discloses a kind of real shortwave protocol sample data processing methods, comprising: obtaining real shortwave protocol sample data set;By anti-fading energy detection method, the burst signal in real shortwave protocol sample data set is sequentially intercepted, and burst signal set is formed;If it is judged that the burst signal is real sample, the center frequency of the real sample is obtained, and the real sample is converted into I / Q burst signal by frequency conversion according to the center frequency;The sampling rate of I / Q burst signal is obtained, and the corresponding low-pass filter is selected according to the sampling rate, and the I / Q burst signal is filtered out by low-pass filter to remove the out-of-band redundant information;The signal amplitude and signal phase between I and Q of I / Q burst signal are sequentially calculated, and the training data is formed according to the arrangement mode of amplitude and phase interleaving.It can solve the problem that the data specification of real shortwave communication protocol in the prior art is not standard, the data amount is not balanced, and the training difficulty is great.
