Title:
SIGNAL PROCESSING DEVICE AND IMAGE DISPLAY DEVICE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2021/221190
Kind Code:
A1
Abstract:
The present invention relates to a signal processing device and an image display device comprising same. A signal processing device according to one embodiment of the present invention comprises: a synchronization unit for performing a Fourier transform on the basis of a received baseband signal; and an equalizer for calculating a channel transfer function value, symbol-based noise, and sub-carrier frequency-based noise on the basis of the signal received from the synchronization unit, and calculating channel state information on the basis of the calculated channel transfer function value, symbol-based noise, and sub-carrier frequency-based noise. Thereby, it is possible to improve the performance for burst noise and narrow band noise.
