Title: Noriyuki Shimanuki: Innovator in Mobile Communication Systems

Introduction

Noriyuki Shimanuki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of mobile communication systems, holding a total of 3 patents. His innovative work has paved the way for advancements in communication technology.

Latest Patents

One of his latest patents is a multicarrier mobile communication system. This invention involves a transmitting unit that divides transmit data into multiple code blocks and encodes each block to generate a transmission signal. The transmitting unit then transmits this signal, while a receiving unit captures it as a reception signal. In cases where errors are detected in the reception signal, the receiving unit sends a retransmission request feedback data, which includes a NACK data and information about the first code block group to the transmitting unit. The system assigns first resources for each code block and adjusts the resources based on the feedback data to ensure efficient retransmission.

Another notable patent by Shimanuki also focuses on a multicarrier mobile communication system. In this case, the receiving unit performs iterative decoding on each code block of the reception signal. The decoding process is terminated for the first code block group without detected errors before reaching a predetermined iteration count. Similar to his previous patent, the receiving unit transmits a retransmission request feedback data when errors are found, allowing the transmitting unit to adjust resources accordingly.
