数值实验中基于matlab的龙格算法(Numerical experiments of Runge matlab-based algorithm)

以高斯函数为载波的PPM调制解调，及于理想误码率曲线相比较的误码率曲线(Gaussian function of PPM modulation and demodulation of the carrier, and the desired BER curves compared to BER curves)

此word中包含很多关于简单的MATLAB习题,希望对大家的学习有帮助!(This word contains a lot about the simple MATLAB exercises, we want to study and help!)

matlab中同步电机在dq轴系下的建模，转子绕组短路定子绕组突然加对称电压，无阻尼绕组，自己用S函数编的，很好用的哦，适用于初学(matlab modeling of the synchronous motor in dq shaft under the rotor winding short-circuit the stator winding suddenly and symmetrical voltage damper winding S function series, very well used, suitable for beginners)

Tamura特征提取中的粗糙度、对比度、方向度的代码(Tamura feature extraction roughness, contrast, orientation, degree of code)

无线信道仿真，针对服从瑞利分布的多径信道进行模拟仿真。(Wireless Channel Emulator for multipath Rayleigh distribution channel simulation.)

说明：  音频水印的matlab相关程序，包括两个部分：小波域音频水印（含修正离散余弦变换）及基于HRT和线性回归检测水印的算法。 (Matlab audio watermark-related procedures, including two parts: audio watermarking in wavelet domain (including MDCT) and linear regression based on the HRT and the watermark detection algorithm.)

界面响应键盘事件，按下键盘时的反应，采用keypressfcn函数(Interface response keyboard events, press the keyboard response, the keypressfcn function)

本工程实现了将三路合成的DSB信号用椭圆滤波器（低通，带通，高通）滤出； 其中的freqz函数，filter函数，fft函数都自己实现。 每种滤波器都分别用专门的函数分别写出，可以模块化。( This project will be three-way synthetic a DSB signal elliptic filter (low pass, band-pass, high pass) filter out Freqz function of which, the filter function, fft function. Each filter are, respectively, with a special function, respectively, to write, can be modular.)
