Latest Patents

Hiroyuki Otsuki holds a patent for a radio apparatus. This invention includes an amplifier, a first mixer, an analog-to-digital converter, a distortion compensator, and an oscillator. The amplifier is designed to amplify the power of a transmission signal. The mixer unit mixes a feedback signal from the amplifier with a local signal of a predetermined frequency. The analog-to-digital converter performs analog-to-digital conversion on the output signal of the mixer unit. The distortion compensator compensates for nonlinear distortion of the amplifier based on a digital signal obtained through the analog-to-digital conversion. The oscillator changes the frequency of the local signal to be mixed with the feedback signal in the first mixer in a time division manner, with frequency spacing corresponding to the sampling rate of the analog-to-digital converter. This innovative approach enhances the performance and reliability of radio communications.
