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.

在本研究计画中，我们致力于设计一个超过3Gbps的超高容量多使用者MIMO无线区域网路系统，以及其在IEEE802.11ac的国际标准化活动。作为学术贡献，我们提出并设计了一个实际的芯片设计，1）一个低灵敏度的非线性预编码，和2）一个认知感8x8 MIMO解码器算法。这些结果已作为建议提交给IEEE802.11ac国际标准化委员会。在我们提出的几个建议中，有两个已被本标准所接受，因此，鉴于国际标准化的贡献，我们的项目目标是成功的。从政府科学战略的角度来看，必须将这种标准化活动作为这种国家预算的一项产出。
