主要用于电子信息工程方向的matlab应用，如数字信号处理、通信系统。(The main direction for Electronic and Information Engineering matlab applications such as digital signal processing, communication systems.)

3D discrete cosine transform

清华大学信号课程第二次实验，内容是基于傅立叶级数的信号分解以及双音频按键音合成(Tsinghua signal course the second experiment, the content is based on the Fourier series of two-tone signal decomposition and synthesis of key tone)

MatLab图形绘制功能口令及代码，很不错，值得看看(MatLab graphics rendering capabilities password and code, very good, worth a look)

车辆matlab操作稳定性仿真分析，本人制作程序，仅供参考。(Vehicle operation stability simulation, it made a program for reference purposes only.)

说明：  注水算法是根据某种准则，并根据信道状况对发送功率进行自适应分配，通常是信道状况好的时刻，多分配功率，信道差的时候，少分配功率，从而最大化传输速率。实现功率的“注水”分配，发送端必须知道CSI。(Water injection algorithm is to allocate transmission power adaptively according to certain criteria and channel conditions. Usually, when the channel is in good condition, more power is allocated, and when the channel is poor, less power is allocated, so as to maximize the transmission rate. To realize the "water injection" distribution of power, the sender must know CSI.)
