Patent ID: 7061996

Claim:
A vestigial sideband (VSB) receiver for receiving signals which are transmitted by being modulated in a vestigial sideband method, comprising: a digital processing part for selecting a desired channel frequency and converting the desired channel frequency to an intermediate frequency to digitize a predetermined pass band of the intermediate frequency; a carrier wave restoring part for extracting pilot components from a signal of the digitized pass band to restore carrier waves; a demodulator for separating components I and Q from the signal of the digitized pass band and multiplying the I and Q components with a complex carrier wave restored in the carrier wave restoring part, to demultiplex the components I and Q to signals I and Q of a base band; and a symbol restoring part for restoring a transmission symbol from the signal I of the demodulated base band output from the demodulator, wherein the digital processing part comprises: a surface acoustic wave (SAW) filter for passing a predetermined band of the intermediate frequency, a digital converter for digitizing signals which are passed through the SAW filter, a digital matching filter for passing a band in which information from the digitized signals exists, and a phase divider for dividing the components I and Q from the signals which passed through the digital matching filter.
