Title: Masanori Hamamura: Innovator in Data Transmission Technologies
Introduction
Masanori Hamamura is a prominent inventor based in Kochi, Japan. He has made significant contributions to the field of data transmission, holding a total of five patents. His work focuses on improving communication systems and methods, particularly in the realm of multicarrier modulation techniques.
Latest Patents
One of his latest patents is a data transmission system and method that utilizes a continuous-phase high compaction multicarrier-modulation (CPPC/HC-MCM). This innovative approach employs a continuous phase modulation (CPM) technique to eliminate amplitude gaps between continuous signals. As a result, it enhances the effective use of frequency bandwidth, achieving a lower bit error rate (BER) for a wide signal-to-noise ratio at a common spectral efficiency of about 0.33 or less, compared to conventional unmodulated PC/HC-MCM.
Another notable patent involves a communication apparatus, communication system, communication method, and computer-readable storage medium. In this system, a receiver is designed for MIMO transmission and includes a filter that processes signals received from a transmitter. The filter updates a weight matrix using an adaptive algorithm for each substream message symbol. Additionally, a code generator feeds back part of the updated weight matrix as an optimized STF code to the transmitter, enhancing transmission based on the current channel state.
