A multi-band receiver according to an embodiment of the present invention includes an analog-to-digital converter configured to convert multi-band analog radio signals into a digital baseband signal, and a first signal extracting unit configured to generate a first path signal by changing a sampling rate of the digital baseband signal and sample-delaying the digital baseband signal, and generate a second path signal by bypassing the digital baseband signal, wherein the first signal extracting unit extracts a first baseband signal using a group delay difference between the first and second path signals caused by a sample delay difference between the first and second path signals.
