Title: The Innovations of Youji Nakata
Introduction
Youji Nakata is a prominent inventor based in Sapporo, Japan. He has made significant contributions to the field of radio communication, holding a total of 3 patents. His work focuses on enhancing the efficiency and effectiveness of wireless communication technologies.
Latest Patents
One of Nakata's latest patents is a radio communication circuit and device. This invention includes a transmitter with a modulator that modulates a signal using a first modulation scheme. The power amplifier then amplifies this modulated signal for transmission. The receiver features a demodulator that demodulates the transmitted signal using a second modulation scheme, which differs from the first. Additionally, a pre-distortion compensator adjusts for any distortion that occurs during amplification, while a power controller manages the power supply to the receiver and compensator based on the signal's average power level and peak-to-average power ratio.
Another notable patent is a wireless communication device designed for calculating the level correction value for transmission signals. In this device, a control unit operates in a correction value calculating mode, flipping switches to the 'a' sides. The modulation processing unit generates a continuous wave (CW) signal, which is then converted from digital to analog by a digital-to-analog converter (DAC). The signal undergoes filtering to eliminate high-frequency components, followed by amplification and down-conversion. A level detecting unit measures the voltage level of the CW signal, and a correction value calculating unit determines the necessary correction value, which is stored for future use.
