Title: Mitsufumi Yoshimoto: Innovator in Digital Modulation Technologies
Introduction
Mitsufumi Yoshimoto is a notable inventor based in Nara, Japan. He has made significant contributions to the field of digital modulation technologies, holding a total of 4 patents. His work primarily focuses on enhancing the efficiency and performance of digital signal processing.
Latest Patents
Yoshimoto's latest patents include a baseband signal generator for digital modulators and a digital DQPSK modulator. The baseband signal generator performs differential encoding and mapping processings for a digital baseband signal. It limits the bandwidths of the obtained symbol mapping data of an I phase and a Q phase using digital filters. Each digital filter accumulates symbol mapping data corresponding to multiple symbol sections and utilizes ROMs to store symbol data for a predetermined filter waveform. The output is a digital baseband signal that is converted into an analog signal for modulation.
The digital DQPSK modulator also limits the bands of symbol mapping data for the I phase and Q phase. It multiplies the obtained data by carrier signals through a digital filter in a time-divisionally multiplexed manner. This modulator includes circuits for accumulating symbol mapping data and ROMs for storing multiplication results, ultimately producing a digital modulated signal that is converted into an analog signal.
