在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案-The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program

具有友好用户界面的嵌入式系统已成为当今嵌入式相关研究的的热点。本文介绍了系统平台构建,分别叙述了嵌入式Linux内核的配置与编译,Qt/Embedded图形界面系统的移植与开发,以及基于嵌入式Linux的无线网络功能模块的开发与实现。运行结果表明,方案合理,运行可靠。-Has a friendly user interface of embedded systems have become embedded in today

本文首先分析Linux2.6.6内核新特性的基础,探讨对Linux进行实时化和嵌入式化,即通过配置内核,裁减shell和嵌入式C库对系统定制,使整个系统能够存放到容量较小的FLASH中。然后简单介绍了防火墙的概念,深入地分析了Linux2.6.6版新型内核防火墙netfilter框架的工作机制及其实现的方式。-In this paper, the kernel Linux2.6.6 the basis of new features to explore on the Linux and embedded real-time, that is by configuring the kernel, the reduction of shell and embedded C library on the system customization, so that the entire system to the capacity to store more FLASH in the small. And then briefly introduced the concept of a firewall, in-depth analysis of the new kernel version Linux2.6.6 firewall netfilter framework of the working mechanism and its implementation approach.
