Abstract: The present disclosure relates to a wireless reception device and an image display apparatus including the same. The image display apparatus includes a first signal converter configured to convert an input signal based on the RF signal into a first baseband signal, a second signal converter configured to convert the input signal based on the RF signal into a second baseband signal, a processor of a first standard configured to perform signal processing on the first baseband signal from the first signal converter based on a first standard, and a first processor of a second standard configured to perform signal processing on the second baseband signal from the second signal converter based on the second standard. Accordingly, the time delay when signal processing is performed on input signals of a plurality of standards is reduced.

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 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.
