Title: Hiroshi Ochi: Innovator in Adaptive Equalization Technology
Introduction
Hiroshi Ochi is a prominent inventor based in Okinawa, Japan. He has made significant contributions to the field of adaptive equalization technology, holding 2 patents that showcase his innovative approach to signal processing.
Latest Patents
Ochi's latest patents include an "Adaptive Equalizer and Designing Method Thereof" and an "Adaptive Equalization Method." The first patent describes an arrangement of an adaptive equalizer with a direct filter structure based on the least mean square error architecture. This invention allows for the look-ahead conversion of modifying a tap coefficient of the next cycle by utilizing the tap coefficient of a predetermined preceding cycle. A retiming process is then carried out to adjust the timing of tap coefficients and signals, resulting in a transposition filter. This high-speed adaptive equalizer reduces the critical path without increasing hardware requirements and offers superior expandability. The second patent outlines an adaptive equalization method that updates the tap coefficient by utilizing the mean value of instantaneous gradient vectors. This ensures the likelihood of pseudo transmission data generated from received data.
