用C++实现视力表的程序，很不错的哦(C realization of the vision chart procedures, very good oh! !)

基于电力系统仿真软件DIGSILENT的一个50台风机的风电场。(Based in wind power system simulation software DIGSILENT a 50 Typhoon aircraft.)

String Builder extends Abstract String Builder implements Appendable.

说明：  两个matlab的GUI实现UDP通讯，建议在两台电脑上测试。(The two matlab GUIs implement UDP communication. It is recommended to test on two computers.)

可以利用MATLAB编写GDSII图形文件，GDSII是一种时序提供格式，用于设计工具、计算机和掩膜制造商之间进行半导体物理制板的数据传输。得以普遍应用，成为半导体工业最常用的文件格式。在成为工业标准之前，GDSII最初始于GE Calma公司。GDSII格式对分布于每一个制作层的电路单元进行全面描述。这种格式是基于二进制的独立平台。电路单元可包含诸如多晶硅（两维域），连线和其他用于分级设计的单元件。(The program can be used to write GDSII format file. GDSII stream format, common acronym GDSII, is a database file format which is the de facto industry standard for data exchange of integrated circuit or IC layout artwork. It is a binary file format representing planar geometric shapes, text labels, and other information about the layout in hierarchical form. The data can be used to reconstruct all or part of the artwork to be used in sharing layouts, transferring artwork between different tools, or creating photomasks.)

这是一个关于ofdm在802.11协议下的源码，很有参考价值，希望对大家有用(This is a matter of OFDM in the 802.11 protocol under the source, a good reference, in the hope that useful)

通信中CDMA模式中的power control(Power control in CDMA mode in communication)

This gives the generation of random integer.

一个获取多个IP地址的源程序，对你可能很实用的。-Access to more than one source IP address, you may be very useful.

说明：  单频信号经过多径时变信道后，输出信号的包络随时间随机起伏，输出信号的频谱从冲激谱变成一个窄带频谱。径数位20，变化频率从0—2HZ随机均匀抽取。(Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into a narrow-band spectrum spectrum. Digital Drive 20, changes in frequency from 0-2HZ uniform random samples.)
