Abstract
An interference detection method and system and for providing information about at least one interference in I/Q data obtained over-the-air or detected on a link between a radio equipment controller (REC) and at least one radio equipment (RE). The method includes noise filtering a set of the FFTs into an averaged FFT, filtering the averaged FFT with a high-pass filter to remove low frequency components, applying a power threshold on the high-pass filtered FFT to select at least one candidate peak having a power greater than the power threshold; outputting information about the at least one candidate peak, which is a potential interference. The interference detection method further includes multi-lane processing and power shift compensation.
