Abstract
The disclosure provides a wireless channel scenario identification method and system. The method includes: simulating different wireless channel scenarios to obtain a channel scenario baseband signal y(t); extracting a feature parameter of y(t), extracting an autocorrelation function A(t)and performing a Fourier transform thereon to obtain a power spectral density function S(t); normalizing S(t)to obtain a normalized channel scenario power spectral density function(t); designing a deep learning network and inputting(t)and a category label pair to train the deep learning network; and for a system with a channel scenario to be identified, collecting a passband signal at its receiving end, obtaining the normalized scenario power spectral density function(t), and using(t)as an input of the trained classifier, the output of the classifier being a label sequence of the channel scenario, and the channel scenario is effectively determined.
