PROBLEM TO BE SOLVED: To provide a method and device for providing interference signal detection in a receiver.SOLUTION: A method and device for interference signal detection includes: sampling an input signal; downconverting and sampling the input signal so as to a sampled and downconverted (SD) input signal; comparing a sampled input signal with a wide-band threshold THand comparing the SD input signal with a narrow-band threshold TH; generating a wide-band (WB) interrupt signal through the comparison with the TH, and generating a narrow-band (NB) interrupt signal through the comparison with the TH; and generating a composite interrupt signal on the basis of at least one of the WB interrupt signal and the NB interrupt signal. |
