Interference detection mechanisms for microwave radio link transceivers

Abstract

A demodulator (310) for a microwave radio link transceiver (110, 300), comprising an input port (311, 312) arranged to receive a radio signal (Din, Sin), a slicer module (313) arranged to detect an information signal (Sdet, 201) comprised in the received radio signal, an interference detection module (314) arranged to determine a difference signal as a difference between the received radio signal (Din, Sin), and the detected information signal (Sdet), wherein the interference detection module (314) is arranged to detect one or more interference signals (202, 203, 204) by identifying signal content comprised in the difference signal, the signal content being associated with a signal power (230) above a pre-determined threshold level (260, 261), wherein the interference detection module (314) is further arranged to associate at least one of the detected interference signals (202, 203, 204) with one or more respective identification features, and wherein the demodulator (310) comprises an output port (315) arranged to output data (400, 450) indicative of the one or more identification features.
