Title: Jounghoon Beh: Innovator in Adaptive Beamforming Technology
Introduction
Jounghoon Beh is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of adaptive beamforming technology, holding a total of 4 patents. His work focuses on enhancing sound source separation and improving the performance of adaptive filters.
Latest Patents
One of his latest patents is titled "Adaptive mode control apparatus and method for adaptive beamforming based on detection of user direction sound." This invention provides an adaptive mode control apparatus that includes a signal intensity detector. The detector searches for signal intensity in designated directions to identify the maximum value when a voice signal is input through at least one microphone. An adaptive mode controller then compares this maximum signal intensity with a threshold value to determine whether to perform an adaptive mode of a Generalized Sidelobe Canceller (GSC). This innovation addresses the limitations of conventional adaptive filters by ensuring that adaptation does not occur when noise from a sound with high autocorrelation is present.
Another notable patent is the "Sound source separation method and system using beamforming technique." This system employs a beamforming technique to separate sound sources effectively. It includes components such as a windowing processor, a DFT transformer, a transfer function estimator, and a noise estimator. The system is designed to extract individual voice signals from integrated voice signals, even when multiple sound sources are present simultaneously.
