Title: Takaaki Konishi: Innovator in Digital Modulation and Demodulation Technologies
Introduction
Takaaki Konishi is a prominent inventor based in Ibaraki, Japan. He has made significant contributions to the field of digital modulation and demodulation technologies. With a total of 12 patents to his name, Konishi has demonstrated a strong commitment to innovation and technological advancement.
Latest Patents
Among his latest patents is an "Apparatus and method for digital modulation." This invention features a first interpolation section and a second interpolation section that perform sampling on input data Id and Qd, having a sampling frequency fover. The resulting data achieves a sampling frequency fsamp, which is equal to the operating clock frequency of a digital-to-analog converter, serving as the output destination. This method effectively interpolates data using a frequency ratio between the sampling frequencies.
Another notable patent is the "Digital demodulation device and synchronization detecting method." This invention addresses synchronization errors that occur when a DTV signal is distorted during transmission, which can impair demodulation capability. The device and method can correct synchronization positions when errors are detected. A controller compares a center tap coefficient from a waveform equalizer with a predetermined threshold. If the coefficient falls below the threshold, the controller identifies a synchronization error and outputs a control signal. The synchronization detector then re-detects the sync signal to correct the error.
