Introduction

Shinichi Aiko is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of adaptive coding and signal processing. With a total of 2 patents, Aiko's work has advanced the technology used in predictive coding and transmission systems.

Latest Patents

One of Aiko's latest patents is a predictive code conversion method capable of forcibly putting a feedback. This invention involves a predictive encoder that encodes an input signal into an output signal while utilizing an adaptive predictive filter. The encoder control circuit monitors the products between the coefficients and tap signals, ensuring that each product is forced to zero when necessary. The feedback loop can be temporarily placed in an inactive state when the predictive signal becomes zero.

Another notable patent is a system and method for ADPCM transmission of speech or similar signals. This adaptive differential pulse code modulation (ADPCM) system includes a subtractor that provides a difference signal between an input signal and a predicted signal. The coder encodes this difference signal for transmission, while a prediction circuit generates a prediction signal based on the reproduced error signal. The control circuit detects transmitter instability, ensuring reliable communication.
