Abstract
A device (1) for reducing the interference in a received communication signal. The device includes: an adaptive filter (2) which uses a self-reference signal to remove a coherent and stable interfering signal from the received communication signal; a detection module (3) for detecting the existence of the target signal among the received communication signals; and a demodulation module (7) for demodulating the received communication signal when the target signal is detected. Further, this device includes: a noise-classifying device (5) which detects various interfering signals of the received communication signal and determines the classification of the detected interfering signals; and a switching module (6) for selecting the input signal for the demodulation module on the basis of the determination made by the noise-classifying device and the value when the existence of the target signal is detected.
