This book intends to prepare you to define unified Communications (UC) for yourself and then get it to work for you. Each vendor pulls together from its available products a package of features related to voice, data, messaging, and image communications. That’s UC for one vendor, but it’s unlikely to match exactly the UC from another vendor. You need a detailed specification to know what you’ll see installed.

Bootloader是微处理器上电时运行的第一段代码，它可以通过通信接口实现对微处理器内部应用程序的更新升级，为网络化嵌入式产品的应用程序升级带来极大的便利。由于目前没有统一嵌入式系统的Bootloader。基于NEC 78K0系列单片机自编程原理，设计出一个适用于78K0/Fx2系列单片机的Bootloader，并能够通过单片机串口在线升级应用程序。 Abstract: Bootloader is the first piece of code executed after microprocessor startup. It makes the embedded product’s firmware update conveniently through communication interface. However， no unified bootloader is available for all kinds of microprocessor products. Based on the principle of self-programming NEC 78K0s’ series， a useful Bootloader which is suitable for 78K0/Fx2s’ series MCU is designed，the design can update the application through serial ports.

Xilinx Next Generation 28 nm FPGA Technology Overview Xilinx has chosen 28 nm high-κ metal gate (HKMG) highperformance,low-power process technology and combined it with a new unified ASMBL™ architecture to create a new generation of FPGAs that offer lower power and higher performance. These devices enable unprecedented levels of integration and bandwidth and provide system architects and designers a fully programmable alternative to ASSPs and ASICs.

为了能够满足基站易于选址、优质快速的建站要求和易维护、低成本、高可靠的运行要求，本文对以方舱来实现一体化结构基站做出一番探讨。从系统设计的观点阐述了移动通信高性能基站天线设计的几个关键问题，介绍了智能天线技术在基站中的应用，并且用HFSS软件仿真了一种新型的对称阵子天线，该天线驻波比小于2的带宽可以达到60%，具有良好的宽频带特性。 Abstract: In order to meet the station construction requirement of easy site selection and fast base station， and meet the operational requirement of easy maintenance， low cost and high reliability， this paper discussed the unified architecture base station using shelter. Several key problems of high performance mobile communication base station antenna were illustrated from the view of system design， the application of smart antenna in base station was also introduced. And a novel dipole antenna was simulated by using HFSS， the VSWR of the antenna is less than 2， and the bandwidth was reach to 60%. So it has good broadband properties.
