Introduction

Hiroto Sakaki is an accomplished inventor based in Tokyo, Japan. He is currently employed at Mitsubishi Electric Corporation, where he focuses on developing advanced technologies in the field of signal processing. Despite having no granted patents to his name, Sakaki has made significant contributions through his latest patent applications.

Latest Patent Applications

Hiroto Sakaki's recent patent applications include innovative technologies aimed at improving signal amplification and distortion compensation. One of his notable applications is for a "Distortion Compensation Device, Distortion Compensation Method, and Transmission Device." This device features an amplification target signal acquiring unit that obtains a signal for power amplification and an operation status signal acquiring unit that monitors the power amplifier's status. The distortion compensation unit estimates the distortion added to the amplification target signal and generates a predistortion signal to compensate for this distortion.

Another significant application is for an "Amplitude and Phase Control Device, Amplitude and Phase Control Method, Amplification Device, and Radio Transmitter." This device includes a signal dividing unit that splits a transmission signal into two, which are then processed by a Doherty amplifier. The error calculating unit assesses the synthesized signal from the amplifier and adjusts the amplitude and phase of the output signals based on the calculated error.

Conclusion

Hiroto Sakaki is a dedicated inventor whose work at Mitsubishi Electric Corporation focuses on enhancing signal processing technologies. His latest patent applications reflect his commitment to innovation in distortion compensation and signal amplification.
