Abstract: The present disclosure relates to a signal processing device and an image display apparatus including the same. A signal processing device according to an embodiment of the present disclosure includes a sampler to downsample a baseband signal; a memory to store the downsampled data; a frequency shifter to read the data in the memory and shift the read data in a frequency domain; a symbol rate calculator to calculate a symbol rate based on the shifted data; a first offset calculator to calculate a first carrier frequency offset based on the calculated symbol rate; a second offset calculator to calculate a second carrier frequency offset based on the calculated first carrier frequency offset; and an offset compensator to compensate for the second carrier frequency offset. Accordingly, a time up to the demodulation completion may be shortened based on the baseband signal.

Abstract: The present disclosure may include receiving, by a terminal in a wireless communication system, at least one reference signal from a base station, generating channel status information after channel measurement based on the at least one reference signal, and giving feedback on the generated channel status information to the base station, wherein the at least one reference signal may be a reference signal that is transmitted from the base station to the terminal through a reconfigurable intelligent surface (RIS), and first beamforming transmitted from the base station to the RIS may be determined based on the feedback.
