Patent number: 8031813Abstract: There are provided a VSB receiver and a carrier recovery apparatus thereof, in which a carrier is recovered using a VSB modulated signal. In the VSB receiver, a digital processing part selects a desired channel frequency through an antenna, converts the channel frequency into an intermediate frequency, and digitalizes the channel frequency by passing a predetermined band of the intermediate frequency. A carrier recovery part extracts pilot signals by using a first LPF having a first bandwidth and a second LPF having a second bandwidth, and recovers a baseband carrier wave signal from a passband signal by using one of the extracted pilot signals. A clock demodulation part removes the pilot signal from the baseband carrier wave signal and extracts a synchronizing signal. A noise removing part removes a linear noise and a residual phase jitter of the baseband signal by using the synchronizing signal. A decoding part decodes the baseband signal whose noise is removed.Type: GrantFiled: June 4, 2009Date of Patent: October 4, 2011Assignee: LG Electronics Inc.Inventors: Joon Tae Kim, Tok Kim

Patent number: 7136111Abstract: A channel equalizer of a terrestrial digital TV receiver using a VSB modulation method is disclosed. By using a precise channel estimator according to the LS method, the transmission channel can be precisely estimated regardless of the characteristic of the transmission channel. By performing the channel equalization in the frequency domain based on the estimated channel, since the channel can be precisely compensated for, and a firm frame synchronization is supplied even to the time-varying multiple path channel, it can be exhibited superior performance even a mobile channel. Moreover, since the FFT implemented by hardware simpler than the transversal filter of the time domain can be used, the equalization is performed not the time domain but the frequency domain, a longer equalizing range can be obtained.Type: GrantFiled: August 1, 2003Date of Patent: November 14, 2006Assignee: LG Electronics IncInventor: Joon Tae Kim

Patent number: 7061996Abstract: A vestigial sideband VSB receiver includes a digital processing part for selecting a desired channel frequency via an antenna and converting the desired channel frequency to an intermediate frequency to digitize a predetermined 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, and a demodulator for separating components I and Q from the signal of the digitized pass band and multiplying the components with a complex carrier wave, which is restored in the carrier wave restoring part. The carrier waves are restored by extracting the pilot signals from the pass band and detecting the symmetrical errors of the carrier wave frequency, so that the carrier wave may be stably obtained and pursued with relation to the both positive and negative frequency offsets.Type: GrantFiled: December 20, 2000Date of Patent: June 13, 2006Assignee: LG Electronics Inc.Inventor: Joon Tae Kim

Patent number: 6882373Abstract: A VSB demodulating device and method in a DTV receiver is disclosed, in which a VSB signal is received for independent carrier wave recovery and symbol clock recovery. An A/D converter samples the output of a SAW filter with a fixed frequency and converts the resultant value to a digital signal. A carrier wave recovery portion recovers a carrier wave from a base band pilot signal output from a multiplier, and a timing recovery portion recovers a symbol clock used for a transmitter using the output of a matched filter disposed in a base band. In this case, the carrier wave recovery portion and the timing recovery portion are independently operated without affecting each other. Thus, the carrier wave recovery portion is operated stably even in case where a fatal ghost exists in a band used for timing recovery.Type: GrantFiled: February 7, 2002Date of Patent: April 19, 2005Assignee: LG Electronics Inc.Inventors: Sung Ryong Hong, Joon Tae Kim
