实现对数压缩PCM和线性PCM的信噪比特性曲线的仿真，非均匀量化级数为n=8和n=6。(realization of a number of PCM compressed and linear PCM signal-to-noise ratio of the characteristic curve simulation, non-uniform quantization Series n = 8 and n = 6.)

白噪声及有色噪声序列的产生，有色噪声序列可以看成由白噪声序列驱动的线性环节的输出(White noise and colored noise sequence generated colored noise sequence can be seen as the output of the linear part of the sequence driven by white noise)

本文详尽阐述了如何在matlab环境下如何使用matlab6.0，教程，word版本(This article elaborates how to how to use the matlab environment matlab6.0, tutorials, word version)

说明：  TSP问题蚁群算法通用Matlab程序源码(Ant colony algorithm for TSP problem common Matlab source code)

The Gaussian blur is a type of image-blurring filter that uses a Gaussian function (which also expresses the normal distribution in statistics) for calculating the transformation to apply to each pixel in the image

通过这一算法可以实现二维平面内无人机的路径规划。在该平面内存在已知的障碍，势场法通过给终点添加引力，对障碍增加斥力，使得无人机能够顺利的避障并到达终点。通过对传统势场法的改进，避免了无人机容易陷入极值的问题，使搜索更易实现。(Through this algorithm, the path planning of the UAV in the two-dimensional plane can be realized. There are known obstacles in the plane. The potential field method adds gravity to the terminal to increase the repulsion for obstacles, so that the UAV can avoid obstacles and reach the terminal smoothly. Through the improvement of the traditional potential field method, it avoids the problem that the UAV is easily trapped in the extreme value and makes the search more easy to be realized.)

说明：  数字信号处理，语音信号的时频分析及滤波恢复 ； 对语音信号进行采样、滤波、加噪等处理，大作业优秀作品(Digital signal processing, speech signal time-frequency analysis and filter recovery; Sample, filter and add noise to speech signal, excellent works of large-scale operation)

说明：  本程序为阵列信号处理中的波达方向角估计的MATLAB程序,可以学习后优化代码.(procedures for the array of signal processing DOA estimation MATLAB, we can learn from optimized code.)

说明：  利用低通滤波器进行横条纹滤除，效果可以，最好进行一下后期处理，效果会更好。(Use of horizontal stripes of low pass filter filter, the effect can be desirable to look at post-processing, the effect will be better.)
