Detection and tracking of interferers in a RF spectrum with multi-lane processing

An interference detection method 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), said I/Q data being provided as a plurality of Fast Fourier Transformation (FFT) streams, said interference causing a peak in said FFT streams the method comprising:

• noise filtering a set of said FFT streams into an averaged FFT;
• filtering the averaged FFT with a high-pass filter to remove low frequency components, thereby producing a high-pass filtered FFT;
• applying a power threshold on the high-pass filtered FFT to select at least one candidate peak having a power greater than said power threshold;
• outputting information about said at least one candidate peak, wherein said at least one candidate peak is a potential interference.
