说明：  matlab开发函数，一些简单的例子和数字滤波器设计函数(matlab development function, some simple examples and digital filter design function)

这是一个完整的无线通信系统中物理层的仿真程序，通过扩频技术（直接序列扩频）让信号通过高斯，瑞利等信道进行信噪比分析，得出结论(This is a complete wireless communication systems in the physical layer of the simulation program, through the spread-spectrum techniques (Direct Sequence Spread Spectrum) to signal through the Gaussian, Rayleigh channel for signal to noise ratio, such as analysis, come to the conclusion)

This text provide good training for general use of Matlab and numerical programing application of Matlab

样本熵程序，本人对其进行了改进，进行了加速。效果不错(the fast of sample Entropy.)

分别利用一维logistic、三维lorenz混沌映射实现任意尺寸彩色图像加密与解密（像素值及其位置都发生了改变）。密钥为混沌序列初始值。（内有详细说明）(Respectively, using one-dimensional logistic, three-dimensional lorenz chaotic mapping to achieve any size color image encryption and decryption (pixel values ​ ​ and their positions are changed). Key to the initial value of the chaotic sequence. (With detailed instructions))

surface acoustic wave device (temp and freq shift)

PCM编解码源程序 很好的程序。谢谢大家进行参考。(PCM codec good source procedures. Thank you for your reference.)

该程序给出了基于AR时间序列建模的陀螺随机漂移模型，并利用卡尔曼滤波方法滤除陀螺随机漂移，经验证，有良好效果。(failed to translate)

说明：  基因算法求f(x）最小值 s.t. l <= x <= u(Gene Algorithm for Finding f (x) the minimum st l &lt = x &lt = u)

用2fsk和2ask调制解调来仿真对语音信号的提取等(With 2 FSK and 2 ask demodulation of speech signal to the simulation of extraction, etc)
