In this research project, we have pursued a design of super-high-capacity Multi-User MIMO Wireless LAN system over 3Gbps and its international standardization activities in IEEE802.11ac. As academic contributions, we have proposed and designed an actual chip design in terms of 1) a low-sensitive non-linear pre-coding, and 2) a cognitive sense 8x8 MIMO decoder algorithms. Those results have been presented at IEEE802.11ac international standardization committee as proposals. Among several our proposals, two of them have been accepted in this standard so that our project aim has been successes in view of international standardization contribution. It is important to pursue such an standardization activity as an output of this kind of national budget in view of a government scientific strategy.

在这个研究项目中，我们研究了超过3Gbps的超高容量多用户MIMO无线局域网系统的设计及其在IEEE802.11ac中的国际标准化活动。作为学术贡献，我们根据 1) 低敏感度非线性预编码和 2) 认知感知 8x8 MIMO 解码器算法提出并设计了实际的芯片设计。这些结果已作为提案提交给 IEEE802.11ac 国际标准化委员会。在我们的多项提案中，其中两项已被该标准接受，因此我们的项目目标在国际标准化贡献方面取得了成功。鉴于政府的科学战略，将这种标准化活动作为此类国家预算的产出是很重要的。
