The Automatic Radio Transmission Systems Recognition

Abstract

This article provides a detailed description of methods for automatic recognition of transmission protocols, used in radio channels, based on distinctive characteristics of the radio signal received as well as binary sequence existing at the demodulator output of the radio recognition receiver. Conclusions are presented as relates to the operational efficiency of the signal analysis methods described, followed by possibilities to use them in practice. A software application has been presented, making use of methods for automatic transmission protocols recognition which are described in this article.

Evaluating Similarity of Spectrogram-like Images of DC Motor Sounds by Pearson Correlation Coefficient

“…The basic region-based image similarity measures are divided into two groups [1]: ED-based and correlation-based measures, where the latter ones provide superior performance in many cases, but they are more computationally demanding. The correlation coefficient and correlation could be used to solve the classification problems [6], [7], as well as for the recognition of radio transmission systems [8]. Correlation is also useful for compression of the speech signal by applying the delta modulation technique [9].…”
