发明名称 METHOD AND DEVICE FOR THE RECOGNITION OF MODULATIONS
摘要 The method consists in computing the following parameters for each transmission spectrum line observed in the determined frequency band: - a mean amplitude of all the lines k of the spectra contained in the determined frequency band - a signal-to-noise ratio RSBk, - a standard deviation ETk in amplitude of each line of the spectrum, - and a coefficient of correlation COR(k,k) of amplitude of each line k with the homologous lines of the transmission spectra contained in the determined frequency band. It also consists in making a comparison, through a network of neurons, of the parameters of each transmission spectrum with expected transmission parameters, and in declaring that a transmission corresponds to an expected transmission when the difference detected by the comparison between the parameters of the transmission and the expected parameters is the minimum.
