摘要： A receiver and a method are applied in a wireless communication system for detecting interference with a coexisting radar system. A signal received from an antenna (100) is fed through an analog part (200) and a subsequent digital part (300) of said receiver. The receiver comprising an element (240, 260) with a-priori known attenuation values for a predefined set of frequencies, a first branch-off element (230, 252) for deriving a first detection signal (S10, S22) from the signal before said element (240, 260) and a second branch-off element (251, 270) for deriving a second detection signal (S21, S30, S20) from the signal after said element (240, 260). Further, the receiver comprising processing means (400) for processing the first (S10, S22) and the second (S21, S30, S20) detection signal such that a difference between the first (S10, S22) and second (S21, S30, S20) detection signal is comparable with a threshold value, wherein the threshold value depends on the a-priori known attenuation values of the element (240, 260). Depending on the comparison result, a frequency is identified as interfering or not a co-existing radar system.
