Title: Innovations of Toshihisa Nishijima
Introduction
Toshihisa Nishijima is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of coding and decoding methods, holding a total of 2 patents. His work has advanced the efficiency and reliability of data transmission systems.
Latest Patents
One of his latest patents is a coding and decoding method. This method involves appending a certain promised nonzero symbol for coding and decoding, which prevents the presence of a codeword with all-'0' data after coding. This innovation allows for the detection of faults in external circuitry by checking for the occurrence of an all-'0' received word attributable to the external circuitry.
Another significant patent is an error correction encoder/decoder. This invention features a separate operational section for determining the degree of a polynomial, which enhances the processing speed in determining both error locator and evaluator polynomials. When decoding a received word based on the found error location, the word is stored in memory, corrected, and output through the designated address. The formula derived from the error locator equation increases the process speed, and the decoder and encoder share part of the hardware to create a compact system.
Career Highlights
Toshihisa Nishijima has worked with prominent companies such as Mitsubishi Electric Corporation and Mitsubishi Electric K.K. His experience in these organizations has contributed to his expertise in the field of data encoding and decoding.
