Latest Patents
One of his latest patents is the VSB receiver and carrier recovery apparatus. This invention provides a method for recovering a carrier using a VSB modulated signal. The VSB receiver includes a digital processing part that selects a desired channel frequency through an antenna, converts it into an intermediate frequency, and digitalizes the channel frequency by passing a predetermined band of the intermediate frequency. The carrier recovery part extracts pilot signals using two low-pass filters (LPFs) with different bandwidths. It then recovers a baseband carrier wave signal from a passband signal using one of the extracted pilot signals. The clock demodulation part removes the pilot signal from the baseband carrier wave signal and extracts a synchronizing signal. Additionally, a noise removing part eliminates linear noise and residual phase jitter of the baseband signal using the synchronizing signal. Finally, a decoding part decodes the baseband signal after noise removal. This innovative approach allows for stable carrier recovery even when the pilot signal is weak.
