c51单片机18B20+lcd1602显示 ，c51单片机18B20+lcd1602显示(18b20 for C51 and lcd1602)

Windows程序运行原理及程序编写流程，窗口产生过程，句柄原理，消息队列，回调函数，窗口关闭与应用程序退出的工作关系，使用VC++的若干小技巧，stdcall与cdecl调用规范的比较，初学者常犯错误及注意事项。(Run Windows program principles and procedures for the preparation process, the process window, handle theory, message queues, the callback function, the application window is closed and quit working relationship, using VC++ several tips, stdcall and cdecl calling conventions comparison, beginners often mistakes and precautions.)

一个很有用的软件,用于耐久性的评定，这是其中的样本文件。(A very useful software for the assessment of durability, which is one of the sample documents.)

uboot--linux -s3c2440-nand_flash,nor_flash,64Msdram.This program is free software(uboot--linux-s3c2440-nand_flash,nor_flash,64Msdram.This program is free software)

音乐播放器，可以从系统中选择想要听的歌曲，导入到该播放器中，播放器有暂停和开始选项。(Music player, you can choose from the system you want to listen to the songs into the player, the player with pause and start options.)

this source is how to get disk list. you will know how to use GetVolumeInformation function.

终于找到了mpsk信号的调制，一家外国网上的，有用的就下，大家多交流啊(Finally found a MPSK signal modulation, a foreign line and useful on the next, more than U.S. exchanges ah)

一个文件管理系统，服务器端 客户端链接之后便可以运行(A document management system, server-side link and then the client can run)

可以动态移动的尺度的设计，适合图形显示和控制(The scale can be designed to dynamically move, for graphics display and control)

说明：  在基于脉冲的UWB系统中，采用瑞克接收机合并多径信号能量并进行相干检测，信道估计问题即估计多径信号的到达时间和幅度。在基于OFDM的UWB系统中，接收机根据信道频域响应对每个子信道进行频域均衡后进行相干检测，信道估计问题即估计信道频域响应。(Pulse-based UWB systems, rake receivers using the combined multipath signal energy and coherent detection, channel estimation problem that is estimated multipath signal arrival time and amplitude. OFDM-based UWB system, the receiver under the channel frequency response of each subchannel to frequency domain equalization after coherent detection, channel estimation problem that is estimated channel frequency response.)
