Patent ID: 7072425

Claim:
A digital TV receiver including an A/D converter, a carrier recovery, and a symbol clock recovery, wherein the symbol clock recovery comprises: an OQAM converter and filter for converting each of the digital base-band real/imaginary signals in a VSB type into OQAM real/imaginary component signals, and performing a high pass-band filtering on the OQAM real/imaginary component signals for removing information of data section; a squaring operator for squaring each of the OQAM real/imaginary component signals outputted from the OQAM converter and filter, and adding and outputting the calculation; a squarer for squaring the signal outputted from the squaring operator, and outputting the calculation for detecting timing error information; and a timing error detector and recovery for detecting timing error information from the squared signal outputted from the squarer, and generating and outputting at least two times the frequency of the symbol clock corrected from the detected timing error information.
