Title: The Innovative Journey of Taku Nagase: A Pioneer in Mobile Communication Technologies

Introduction

Taku Nagase, an accomplished inventor based in Tokyo, Japan, has made significant contributions to the field of mobile communication with a total of 15 patents to his name. His innovative work primarily focuses on enhancing communication technologies, particularly in the context of 3GPP mobile communication systems.

Latest Patents

Among his latest patented inventions is a method and apparatus for performing turbo encoding in a 3GPP mobile communication system. This innovation includes a communication terminal device featuring a turbo encoder that executes two systems of convolutional encoding on input data. It preforms turbo encoding processing with in-block interleaving on one of the two systems using an internal interleaver. Additionally, the design incorporates rate matching (puncturing) units to puncture the turbo encoder's output based on a set rate matching algorithm, thereby optimizing turbo code performance.

Another notable patent developed by Nagase is a retransmission ordering method for wireless communication systems, which encompasses a receiver and transmitter. This system encodes frame data with an outer code and subsequently divides it into a predetermined number of blocks, which are encoded with an inner code into transmission data. A decoder in the receiver decodes this data based on the inner code while a retransmission order determining unit assesses the need for retransmission based on the likelihood information derived from the decoded soft-decision value.
