Latest Patents

One of Ki-dong Kang's latest patents is the "Quadrature phase shift keying demodulator of digital broadcast reception system and demodulation method thereof." This invention involves a demodulator designed to process digital broadcast signals effectively. The QPSK demodulator includes an in-phase/quadrature (I/Q) detector that generates baseband I and Q signals by multiplying a modulated QPSK signal with an I/Q carrier signal. Additionally, a bandwidth adjustable first filter is employed to reject imaginary noise from the received signals, ensuring data integrity.

Another notable patent is the "Apparatus and method for pilot-less carrier acquisition of vestigial sideband (VSB) signal." This method addresses the challenges of demodulating a carrier wave in environments where pilot signals may be distorted. It provides a solution for digital TV receivers that receive VSB modulated signals. The invention utilizes a field synchronization part of a VSB signal as a reference for synchronization, estimating frequency and phase offsets through a pilot-less frequency and phase locked loop (FPLL).
