multiuser cdma detection in cdma

1, 2 and 3-D FDTD code with PEC boundaries Program author: Susan C. Hagness

双音多频，由高频群和低频群组成，高低频群各包含4个频率。一个高频信号和一个低频信号叠加组成一个组合信号，代表一个数字。DTMF信号有16个编码。利用DTMF信令可选择呼叫相应的对讲机。(Dual tone multi-frequency, high-frequency and low-frequency group composed of groups, high-frequency group contains four frequencies each. A high-frequency signal and a low frequency signal is superimposed to form a combined signal representative of a number. DTMF signal has a 16 code. DTMF signaling to the appropriate use of the intercom call.)

这是一段去噪程序，与图像修补相关但不是修补代码，有一定的参考价值(Denoising procedures)

采用信号包络和差分方式进行信号模式识别，通过变换产生时域解析信号SKH ，即信号的复包络，得到零中心归一化瞬时绝对值的标准偏差。 (Differential use of signal envelope and the way the signal pattern recognition, transformation generated by time domain analytic signal SKH, the signal complex envelope, zero-center normalized standard deviation of the instantaneous absolute value.)

Herewith i attached the files for contingency, bus impedance matrix,short circuit fault current and swing curve

SMITH算法，计算归一化阻抗，电流，电压，离负载的距离等等(SMITH algorithm, calculation of normalized impedance, current, voltage, distance from the load and so on)

matlab环境下的程序对数据进行标准化，此程序简单易懂，效率也非常高，是一个非常好的程序代码，非常值得推荐！(matlab environment, the data standardization process, this process easy to understand, efficiency is very high, is a very good code, very recommendable!)

求不规则波导的散射参数的matlab程序，使用的matlab的微分工具箱（有限元法），总的来说还不错，附带实验报告。(Scattering parameters of irregular waveguides matlab program, using a differential matlab toolbox (finite element method), on the whole pretty good, with a test report.)
