Communications Unit and Method for Detecting Pulse Interference

摘要

A communication method for use in a first cellular communications system is proposed for minimizing the interference caused by strong interfering pulses in the same frequency band as the system or an adjacent frequency band. The method comprises the steps of receiving an incoming signal bandpass filtering the incoming signal to filter out a first frequency band (B1) used by the communications system and forwarding the bandpass filtered signal to a receiver unit (35) for processing and forwarding the processed signal to a signal detector (37) arranged to detect the wanted signal. Redirecting a fraction of the received signal and detecting the power of the redirected fraction. Using the detected power to modify the function of the signal detector (37).
