Title: Takuya Shimura: Innovator in Acoustic Communication
Introduction
Takuya Shimura is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of acoustic communication, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
His latest patents include an acoustic communication method and an acoustic communication system. The acoustic communication system consists of a first acoustic communication apparatus and a second acoustic communication apparatus. The first apparatus transmits a first acoustic wave to the second apparatus, which then responds by transmitting a second acoustic wave back to the first apparatus. This process continues in constant cycles until the next first acoustic wave is received. Each cycle comprises a transmission period and a pause period. The first apparatus, upon receiving the second acoustic wave, determines the optimal timing for the next transmission based on the time required for the first wave to reach the second apparatus and the length of the transmission period.
Another significant patent involves a receiving device and method designed to efficiently compensate for the effects of Doppler shift. This device includes a Doppler estimator that estimates the Doppler-shift frequency of a received signal. A multiplier and a low-pass filter (LPF) detect the received signal based on the carrier frequency and the estimated Doppler-shift frequency. A timing corrector adjusts the timing for extracting symbols from the received signal, allowing for accurate tracking of the Doppler shift. The symbol extractor then extracts the received symbols, and an adaptive equalizer estimates and determines the symbols from the extracted data.
