Patent ID: 7558340

Claim:
A VSB (vestigial sideband) receiver comprising: a signal converter for outputting a baseband signal by multiplexing a digitized passband signal by a complex carrier according to a phase error; a first phase error detecting part for filtering a pilot signal from the baseband signal by using a LPF (Low Pass Filter) having a first bandwidth and detecting a first phase error from the filtered pilot signal; a second phase error detecting part for filtering the pilot signal from the baseband signal by using a LPF having a second bandwidth and detecting a second phase error from the filtered pilot signal; a phase error outputting part for calculating a power of the pilot signal, comparing the calculated power of the pilot signal with a preset threshold value, selecting the first or the second phase error according to the result of the comparison, and outputting the selected phase error; a complex carrier generating part for generating the complex carrier based on the selected output phase error and outputting the generated complex carrier; a clock demodulation part for removing the pilot signal from the baseband signal output from the signal converter and extracting a synchronizing signal; a noise removing part for removing a linear noise and a residual phase jitter of the baseband signal by using the synchronizing signal; and a decoding part for decoding the baseband signal from which noise has been removed.
