Title: Innovations by Kouji Okamoto: A Focus on Distortion Compensation
Introduction
Kouji Okamoto, an accomplished inventor based in Osaka, Japan, has made significant contributions to the field of distortion compensation technology. With a portfolio of 22 patents, Okamoto's innovations focus on improving the accuracy and efficiency of signal processing systems.
Latest Patents
Among his latest inventions is a groundbreaking distortion-compensation device and method. This apparatus minimizes the storage space required for the coefficients necessary for distortion-compensation calculations. By executing distortion compensation accurately, it enhances the performance of output signals from predetermined circuits. The first multiplication section of this device multiplies an input signal by a selectable first coefficient that aligns with the input signal. Moreover, the second multiplication section processes a delayed version of the input signal to add another layer of adjustment through a tap coefficient. The output signal, generated by combining these multiplications, communicates effectively with the predetermined circuit.
Another notable invention is a distortion compensation apparatus designed to appropriately generate distortion-compensation coefficients. This innovation aims to achieve desired transmission outputs while substantially reducing power leakage to adjacent channels. The reception section of this apparatus captures and demodulates a transmission signal, leading to the creation of a refined demodulation signal. By employing a delay adjustment section, the delay of this signal in relation to the baseband signal is computed and eliminated, ensuring that both signals are synchronized for optimal performance.
