说明：  利用MATLAB语言编写的直流电动机瞬态运行特性分析的程序(The use of MATLAB language to run the DC motor characteristics of the transient process)

vc调用matlab引擎的，图文并茂的介绍操作步骤，并给出简单的调用程序(vc call matlab engine, illustrated introduction to the steps, and gives a simple procedure call)

小波包分解重构程序，克服小波分解在高频段的频率分辨率较差(Wavelet packet decomposition and reconstruction program, overcome the wavelet decomposition in the poor frequency resolution in high frequency )

频域内低通滤波实现图像平滑，程序原代码来自书籍，《计算机图像处理与识别技术》，作者王耀南等(frequency low pass filter)

gps的信号发生方式，直接生成它的信号，还是有一定的参考价值的(gps signal generating means, direct generation of its signal, or have a certain reference value)

该程序利用多相滤波结构实现了宽带信号的信道化，相比传统信道化方法，节省了资源，提高了效率。(The program uses the polyphase filter structure to achieve a broadband signal channelization, compared to traditional methods channel, save resources and improve efficiency.)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元数为10，快拍数为200，信噪比为20dB，阵元间距分别为 tambada/6 tambada/2、tambada。(Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element number 10, the number of snapshots for 200, SNR is 20dB, respectively array element spacing  tambada/6 tambada/2, tambada.)

OFDM记忆多项式功率放大器模型。能够精确的完成对功率放大器的建模，无任何错误。(To achieve the wiener model pre-distortion, the effect is very good, the program checked for any errors)

用 MATLAB 实现简单的信道估计 用 MATLAB 实现简单的信道估计 (channel estimated)

角点提取的源码，其中有错误，已经修改过了，有注释，希望对大家有帮助！！(Corner extraction of source, including errors, has been modified, annotated, we want to help! !)
