Popis:	Many modulated communication signals exhibit a cyclostationarity (or periodic correlation) property. To exploit the underlying periodicity of the modulated signal in the real-time recognition scheme of radio environments, this letter introduces a spectral correlation method to identify the number and the direction of multi-path in the environment of frequency-selective fading channel. By simulation, the graphs of spatial spectra corresponding to a certain cycle frequency is presented to show the accuracy of spectral correlation method in multi-path environment recognition.
