Title: **Innovations of Mitsuru Tsuboi in Voice Coding Technology**
Introduction
Mitsuru Tsuboi is a prominent inventor based in Kawasaki, Japan, known for his contributions to voice coding technology. With a total of 5 patents to his name, Tsuboi has been pivotal in developing innovative solutions that address synchronization issues in voice communication systems.
Latest Patents
One of Tsuboi's latest inventions is an apparatus designed specifically for synchronizing a voice coder and a voice decoder. This advanced system operates on the vector-coding principle and is engineered to prevent false synchronization, even when a signal possesses the same periodic characteristics as a string of synchronizing bits. The innovative aspect involves a noise component adding unit, which adds noise to the input voice signal, effectively disrupting periodicity. This allows a vector-coding unit, alongside a quantizing signal vector generating unit, to produce code book indexes that are transmitted to a voice decoder, thereby ensuring accurate operation without the risk of false synchronization.
Another significant patent focuses on a coding and decoding apparatus that generates code information representing various quantization points of an input signal. This apparatus synthesizes the generated code information into a unified code, further enhancing the efficiency and reliability of voice coding systems.
