Method and the device which use the randomization Hough transform in order to detect the radio system by periodic radiating pattern

摘要

As for this invention, method and the device which identify the transmission opportunity in radio network are included. This method and the device, watching 1st, 2nd and 3rd time period, detect the 1st, 2nd and 3rd busy slot. The processor, recognizes the sequence of the 1st, 2nd and 3rd busy slot randomization Hough transform (Randomized Hough Transform) does in this sequence, as function of time, generates the histogram on the basis of this randomization Hough transform, identifies the peak in this histogram, it decides, identifies the transmission opportunity whether or not this peak corresponds to the known radar.
