Using the similar method, we can use MUSIC spectrum to coarsely estimate the location of the interference source. The BS can divide the space into many small grids and select some known locations as interference sources to build the known MUSIC spectrums related to these selected locations as fingerprint samples. For the localization of the interference source randomly generated from unknown location, BS just calculates the correlation values between these known MUSIC spectrums and this new MUSIC spectrum intended for localization and find the maximum one. Then the location is decided with the selected position of the grid which has the maximum correlation value. Since the interference sources are randomly from the space, the method only coarsely detects the location of interference source. |
