Abstract:
A multiband Orthogonal Frequency Division Multiplexing (OFDM) receiver, and more particularly, a receiver and method for effectively compensating for a frequency offset of a received signal in a multiband OFDM scheme. The receiver for compensating for a frequency offset of a received signal in an OFDM scheme includes: a numerically controlled oscillator (NCO) which generates a first compensation signal by processing an input signal in a time domain based on a first carrier frequency offset estimated in the time domain, and a second carrier frequency offset estimated in a frequency domain; a sampling frequency offset tracking (SFOT) unit which generates a second compensation signal by estimating a sampling frequency offset from frequency domain pilot symbols contained in the first compensation signal; and a carrier frequency offset tracking (CFOT) unit which estimates the second carrier frequency offset by using pilot symbols contained in the second compensation signal.
