Title: Innovations by Joon Tae Kim
Introduction
Joon Tae Kim is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of signal processing, particularly in the development of methods for VSB (Vestigial Sideband) receivers. With a total of 10 patents to his name, Kim's work has advanced the technology used in digital communications.
Latest Patents
One of his latest patents is titled "Carrier phase independent symbol timing recovery methods for VSB receivers." This invention provides a novel symbol timing recovery method that ensures accurate symbol timing even in the presence of residual carrier phase offset. The system includes a timing error detector (TED), a loop filter, a Voltage/Numerically Controlled Oscillator (VCO/NCO), an A/D converter, and an interpolating squared root raised cosine filter. The TED utilizes both in-phase and quadrature-phase components of the received VSB signal, operating at twice the symbol frequency, which enhances the performance of the receiver.
Another significant patent is "VSB receiver and carrier recovery apparatus thereof." This invention describes a VSB receiver that recovers a carrier using a VSB modulated signal. The digital processing part of the receiver selects the desired channel frequency, converts it to an intermediate frequency, and digitalizes it. The carrier recovery part extracts pilot signals and recovers a baseband carrier wave signal, ensuring stable performance even when the pilot signal is weak.
