A signal receiver includes a demodulator, a narrow-band interference detector, and a control module, where the demodulator is for performing signal demodulation upon a received communication signal, the narrow-band interference detector is for performing narrow-band interference detection and accordingly generating a detection result, and the control module is for controlling an operation of the demodulator according to the detection result. In addition, a narrow-band interference detector includes an input port and a processing circuit, where the input port is coupled to an equalizer included in a signal receiver for receiving a signal generated from the equalizer, and the processing circuit is coupled to the input port for performing a narrow-band interference detection according to the signal generated from the equalizer, and accordingly generating a detection result.
