Latest Patents

Naito holds a patent for a signal processing system and information storage medium. According to one embodiment of his invention, a first encoder encodes main information while a second encoder encodes sub-information. A first modulator modulates a carrier based on the output of the first encoder. Additionally, a duplicating module generates encoded sub-information units by duplicating the output of the second encoder. The second modulator then amplitude-modulates the output of the first modulator based on these encoded sub-information units. Notably, the second modulator operates with a noise power of a transmission path or storage medium being σ, and the number of encoded sub-information units is N. The signal levels after amplitude modulation correspond to bit A and bit B of the encoded sub-information units, with a level difference of A−B being μ. This innovative approach allows for improved efficiency in signal processing.
