MIMO指多输入多输出，MIMO技术大致可以分为两类：发射/接收分集和空间复用。传统的多天线被用来增加分集度从而克服信道衰落，具有相同信息的信号通过不同的路径被发送出去，在接收机端可以获得数据符号多个独立衰落的复制品，从而获得更高的接收可靠性。这种技术往往要结合多天线技术，而多天线技术在移动通信中得到了广泛的研究。(MIMO refers to Multiple Input Multiple Output, MIMO technology can be broadly classified into two categories: transmit/receive diversity and spatial multiplexing. Traditional multi-antenna was used to increase the degree of diversity to overcome channel fading, the signal with the same information through different paths have been sent in the receiver-side data symbols can be multiple independent copies of the decline, which was higher reception reliability. This technology often have to combine multi-antenna technology, and multi-antenna technology in mobile communication has been widely studied.)

ARINC-美国航空无线电通信公司（Aeronautical Radio Inc），美国军队的长期合作伙伴。ARINC664系列协议是ARINC公司负责制定的下一代航空数据网络标准。该规范分为8个部分，从不同层次对航空数据网络标准的各个方面进行了系统的定义，形成了以AFDX技术为核心的下一代航空数据网络的完整标准。(ARINC-Aeronautical Radio Inc, the U.S. military long-term partners. ARINC664 series protocol is ARINC company is responsible for the formulation of the next generation of airborne data network standard. This specification is divided into eight parts, from different levels of airborne data network standard all aspects of the definition of the system, formed the AFDX technology at the core of the next generation of airborne data network complete standard.)
