1. A method of processing a signal in a compressive sensing receiver, the method comprising:
obtaining a first signal received via an antenna;
generating a first baseband signal by mixing the first signal with a second signal generated by a local oscillator based on a pseudo random binary sequence (PRBS);
removing a spurious component from the first baseband signal based on a value which is obtained by estimating the spurious component generated by the local oscillator and is stored in advance;
detecting a spectral slice including the first signal based on the first baseband signal from which the spurious component is removed and a measurement matrix, and
calibrating the measurement matrix using a calibration signal generated based on a bit pattern length of the pseudo random binary sequence and a reception frequency band.
