Title: Yoichi Sato: Innovator in Data Transmission Technologies

Introduction

Yoichi Sato is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of data transmission technologies, holding two patents that showcase his innovative approach to signal processing.

Latest Patents

Sato's latest patents include a data transmitting method and a data transmitting apparatus. The first patent describes a serial-parallel converter/encoder unit that inputs transmission symbol data at a transmission symbol rate that is one-Nth of a base-point symbol rate. A precoder/collator creates a transmission symbol waveform at the base-point symbol rate, which becomes a transmission signal after passing through a roll-off filter and a modulator. The reception signal is demodulated by a demodulator and input to a fractionally-spaced equalizer that operates at the base-point symbol rate. The output signal is then processed to determine the reception symbol data.

The second patent focuses on a signal transmission apparatus that comprises a correlator for shaping the spectrum of a signal. This apparatus includes a precoder that subtracts an output signal of a feedback filter from an input signal, along with a modulo arithmetic unit and a feedback filter with a specific transfer function. The correlator can freely shape a transmission signal spectrum, allowing for the suppression of external noise.
