WAVE LET PID FOR aqm

二阶系统的最小二乘一次完成算法辨识程序；主要根据实验室对数据处理的程序改的(A complete second-order system least squares algorithm for identification procedures mainly based on laboratory data processing procedures reform)

这是数字信号处理的好资料，详细地介绍如何用MATLAB进行信号分析与处理，想学习的可以下载看看。(This is good information on digital signal processing, detailed information on how to use MATLAB for signal analysis and processing, want to study can be downloaded to see.)

实用图像处理教程，是这方面的经典教程，适合通信的同学继续学习(Practical image processing tutorial, this classic guide for communication students continue to learn)

产生宽带QPSK信号，并通过rrc滤波，用于检验发射通路的EVM等指标(Produce wideband QPSK signals, and by rrc filter, used to test the emission path of EVM and other indicators)

美国人写的matlab教材，非常好，简单易懂(Americans matlab written materials, very good, easy to understand)

说明：  航天器动力学中用于计算E角各种方法MATLAB程序，包括迭代法，几何法等等(Spacecraft Dynamics various methods used to calculate the angle E MATLAB program, including the iterative method, geometric method, etc.)

无限长的序列也往往可以用有限长序列来逼近。对于有限长的序列我们可以使用离散傅立叶变换（DFT）。DFT是对序列傅立叶变换的等距采样。是序列傅立叶变换的等距采样。 本源码是对DCT、DFT、FFT的matlab实现(Infinitely long sequence is often a long sequence with limited approximation. For the finite length of the sequence we can use the discrete Fourier transform (DFT). DFT is a sequence of equidistant sampling Fourier transform. Is a sequence of equidistant sampling Fourier transform. The source is the DCT, DFT, FFT in matlab implementation)
