自由空间路径损耗

运用matlab搭建了MIMO—OFDM系统，并仿真了该系统在awgn信道，平坦衰落和多径信道下的误码率。(Using matlab built a MIMO-OFDM systems, and simulation of the system in awgn channel, flat fading and multipath channel BER.)

信道检错编码，CRC编码，包括详细的注释，很不错的程序(Channel error detection codes, CRC codes, including detailed notes, a very good program)

这个是华为的VoIP文档，讲述清晰，值得阅读！(This is Huawei' s VoIP documents, about clarity, it is worth reading!)

74汉明码的编解码和性能曲线,程序能够运行，且有注释(74 HAMMING CODES AND PERFORMANCE CURVES)

说明：  通过单元方向图计算并仿真天线阵列的辐射性能，能够模拟相控阵天线扫描方向图。(The scanning pattern of phased array antenna can be simulated by calculating and simulating the radiation performance of the antenna array.)

本章介绍了用于WAN(广域网)环境的各种协议和技术。在这里概述的题目包括点对点链路，电路交换，分组包交换，虚电路，拨号服务，和WAN设备。在手册第3部分,‘WAN协议’,的各章里将更详细地讲述专门技术。 ( This article introduces the various protocols and technologies used in wide-area network (WAN) environments. Topics summarized here include point-to-point links, circuit switching, packet switching, virtual circuits, dialup services, and WAN devices. Chapters in Part 3, “WAN Protocols,” address specific technologies in more detail. )

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.)
