低電力超高速無線通信システムの研究 Research on low-power ultra-high-speed wireless communication systems
高度情報化社会のニーズに応じて、低消費電力、高速無線通信システムが必要になった。ホームネットワーク用途にターゲット、802.11規格に準拠するシステム検討した。回路方式の研究により、低消費電力や高速の付加価値を創ることで、モバイル環境に耐えれるコグニティブ（自律最適化）OFDM無線通信方式の可能性を研究した。
具体的な研究テーマは、
- 600Mbps無線システムの研究、開発、試作（MAC、PHY OneChip)
- MIMO(Multi-In Multi-Out) システムの研究、開発、試作
- コグニティブ無線通信システムの構築法
In response to the needs of an advanced information society, low-power, high-speed wireless communication systems are now required. We investigated a system that complies with the 802.11 standard, targeting home network applications. By creating added value such as low power consumption and high speed through research into circuit methods, we investigated the possibility of a cognitive (autonomous optimization) OFDM wireless communication system that can withstand mobile environments. Specific research themes are:
- Research, development, and prototyping of 600Mbps wireless systems (MAC, PHY OneChip) .
- Research, development, and prototyping of MIMO (Multi-In Multi-Out) systems.
- How to build a cognitive wireless communication system.
