闻亭公司培训DM642的内部资料一共有五天，里面包含讲解的ppt,文档，开发工具，课堂源码例子等。这是第一天内容.(Wintech DM642 training information, total of five parts, which contains explanations ppt, documentation, development tools, source code examples of class and so on.This is the first part. )

计算电磁学，本程序用于电场积分方程求解圆柱散射。(Electric field integral equation (EFIE) for 2-D cylinder scattering. )

说明：  支持向量机入门，以精简的语言描述支持向量机算法的原理和功能。(Support vector machine entry, in order to streamline the language to describe the principle of support vector machine algorithm and function.)

此程序只要实现了MIMO中的LMS自适应均衡(This program as long as the realization of the MIMO LMS Adaptive Equalization in)

利用matlab工具编程播放一段卡农音乐，乐曲部分可任意修改(Programming using matlab tool plays a Canon music, song and part can be freely modified)

In mathematics, a Taylor series is a representation of a function as an infinite sum of terms that are calculated from the values of the function s derivatives at a single point.

利用随机序列进行间隔控制，选择消息隐藏位(Intervals using random sequence control, select the message hidden bits)

用matlab结合窗函数法、等波纹设计法实现FIR滤波器(Combined with matlab window function method, such as corrugated FIR filter design method)

粒子滤波方法用于跟踪，很易看懂的程序，建议初学者下载学习(Particle filter for tracking, it is easy to understand the procedures recommended for beginners to learn to download)

功率谱估计 信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Power spectrum estimation signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signal are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. Is the sampling frequency. Levinson recursive method were used and Burg method for power spectrum estimation, and change the length of the data analysis, the impact on the estimation model order spectrum.)
