Title: Hiromi Miyamoto: Innovator in Distortion Compensation Technology
Introduction
Hiromi Miyamoto is a notable inventor based in Kawasaki, Japan. She has made significant contributions to the field of distortion compensation technology, holding a total of 4 patents. Her work focuses on enhancing the performance of communication systems through innovative solutions.
Latest Patents
Miyamoto's latest patents include a distortion compensation apparatus and a distortion compensating amplifier. The distortion compensation apparatus is designed to adaptively correspond to the number of carriers. It features a distortion compensation processing circuit that multiplies an input signal by a distortion compensation coefficient. Additionally, it includes a distortion compensation coefficient storage that stores the coefficient based on the input signal power. A distortion compensation coefficient calculator updates the coefficient using input and feedback signals. The apparatus also has a digital filter that processes the output of the distortion compensation circuit, along with a modifying unit that adjusts the digital filter's passband to reduce distortion compensation control bandwidth.
The distortion compensating amplifier is another significant invention by Miyamoto. It includes a distortion compensator that updates distortion compensation coefficients to minimize the difference between a transmit signal and a feedback signal. The amplifier then amplifies the compensated transmit signal for transmission. A feedback unit monitors unwanted-wave signals and adjusts the processing of distortion compensation coefficients based on their levels.
