Title:
SIGNAL PROCESSING DEVICE AND IMAGE DISPLAY APPARATUS INCLUDING THE SAME
Document Type and Number:
WIPO Patent Application WO/2020/045866
Kind Code:
A2
Abstract:
The present invention relates to a signal processing apparatus and an image display apparatus including the same. The signal processing apparatus for processing a baseband signal demodulated from an RF signal, includes: a synchronizer; a channel estimator; an equalizer; an error corrector to perform error correction based on a signal output from the equalizer; and a mean square error calculator to calculate a mean square error based on a difference between an input signal input from the equalizer and a reference signal, wherein when the RF signal includes a co-channel interference signal, the error corrector performs error correction by using a mean square error in a time domain or mean square errors in a time domain and a spatial domain. Accordingly, a baseband signal, from which a defect is removed, may be obtained in response to various communication channels or broadcast channels.
