Outline of Research at the Start

無線通信における通信端末数やデータ流通量は急速に増加しており、伝送レートの更なる向上が必要である。本研究では電磁材料・メタサーフェスから構成される通信デバイスを実現し、新たな自由度に基づく多重化によって、伝送レートの向上を目指す。本研究では、まず通信デバイスの基礎となる電磁材料を開発する。次に考案デバイスの通信特性を評価する。最終的には達成可能な伝送レートを解明する。

Outline of Final Research Achievements

The objective of this study lies in developing a novel multiplexing technique based on "pulse width", a parameter independent of existing multiplexing parameters, such as time, space and frequency. Put simply, the use of the pulse width enhances the degree of freedom in wireless communications. To initiate the pulse division multiplexing, we have developed a filtering system capable of separating different pulses arriving at the same time. The proposed system has been verified through numerical and experimental demonstrations. Our results confirmed that pulses with varying widths can be retrieved separately, even when they have the same frequency.

Academic Significance and Societal Importance of the Research Achievements

近年の5G、6G、IoTなどを始めとした、無線通信の先端技術に対する需要はこれまでに無い高まりを見せている。例えば、IoT機器は年間20億台以上のペースで増加し、ひと月あたりのデータ流通量も今後5年間で現在の3倍超になると予測されている。本研究を発展させ、真にパルス分割多重化の技術が完成されれば、新たな多重化方式として伝送レートを飛躍的に向上できると期待される。
