Outline of Final Research Achievements

The purpose of this research is to improve the connectivity of wireless networks under the dense environment of terminals.
First, in a downlink multi-user system, we proposed an efficient Overloaded MIMO interference cancellation method and its transmission-side precoder when inter-user interference occurs on multiple terminals, and confirmed the effectiveness by computer simulation. In addition, as its application, it was applied to scalable MPEG4 high-definition video transmission, and with the same transmission power, high-quality wireless video transmission with a communication distance extended by about 1.4 times compared to general MIMO wireless systems was realized.
Finally, the LSI design of the above algorithm was implemented, and even the logic verification was performed.

Academic Significance and Societal Importance of the Research Achievements

本研究は、端末の稠密環境下における無線ネットワークの接続性改善に関する内容である。具体的には、マルチユーザMIMO無線システムにおける高精度チャネル推定機能を備えたユーザ間干渉の効率的な除去アルゴリズムの開発と、そのLSI化設計まで実施した。学術的な特色は、これらの研究成果をIEEE802.11無線LAN国際標準化委員会に提案を行い、日本の技術のグローバルスタンダード化に寄与できたことにある。
