直接运用 WINSOCK 单元进行传送文件的程序，特点： 1、多线程 2、支持断点续传。 3、系统托盘。 程序在Winxp和Win2000运行通过。 程序用到了第三方控件“VCLSkin2.45.D67”到相关站点可下载。-direct use of Winsock modules for document transmission procedures, characteristics : 1, 2 multithread support HTTP. 3, the system tray. Winxp and procedures in running Win2000 through. Procedures used a third-party control "VCLSkin2.45.D67" related to the site can be downloaded.

此程序参照了IEEE 802.11a ，使用了52个子载波。理论期望papr为52.但是由加扰器的存在，所有子载波很难一直的调制-Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely.

本程序采用了以太网编程，是客户端，可以在任何PC机上运行。-the adoption of the Ethernet programming, client, in any PC running.

远程GPRS注册显示，选中注册的远端。可以进行远程数据下载。-Show long-range GPRS registration, check the registration of the remote. Remote data can be downloaded.

一个真正SERVER PUSH的聊天室，很不错，C语言所写，最可惜的是已经被编译过了，但是界面全部被独立出来了的，可以自行更改，只是不能研究程序的内部结构…… -a real SERVER PUSH chat rooms, very good, C language written, it is most unfortunate that has been compiled, but the interface were all independent of and can make changes, but the procedures are not able to study the internal structure of ...

VHDL语言实现了IS-95标准中的48阶成型滤波器。工作速率80Mbps。接收发送端均可使用。-VHDL Language realize the IS-95 standard of 48 bands forming filter. Work rate of 80Mbps. Can be used to receive the sending end.

这个项目是在 matlab 环境中完成的。它基于在 awgn 信道下使用 BPSK 和 4-QAM 的 ofdm 系统的性能研究。小信噪比的价值相当大的计算的误差 ratewas 和 ISI 制得由于相对高次幂的噪音。SNRwas 增加错误率下降，如预期。事实上，SNRvalue 大于 8 分贝，误差是零。
