matlab实现矩形脉冲和根升余弦脉冲的QPSK调制功率谱密度及不同信噪比信道下的星座图，直接运行main函数即可(Plot the power density spectrum of the transmitted signal (e.g., with the matlab function psd) with different pulse shapes. How is it affected if a root raised cosine pulse is chosen instead of a rectangular pulse shape? Study the signal constellation in the receiver for various values of Eb/N0 for the AWGN channel. )

说明：  为建立供热管网的在线优化运圩、故障实时诊薪 及赏真分析和培训呆缆，必须建立一种高精度的蒸巍供热管 习动恋仿真模型。该模型将蒸汽处理成为单相可压缩洗件， 将营罔处理成为由节点南支路组成的一种网络结构。在仿真 计算中，采用隐式Euler算法、线性迭代方法和稀疏矩畦算 法隶解由物理模型所得的非线性擞分方程组。证明7|：角的 算法具有大范围收敛特性。此方法祷被应 于青岛百蒸汽供 热管网的工程项目中。(Steam heating network of dynamic simulation modeling)

说明：  基于局域法多步预报模型的混沌时间序列预报模型，对多个典型混沌序列的仿真测试表明，本算法具有良好的多步预测精度和较好的抗噪声能力(based multi-step prediction model of chaotic time series prediction model, a number of typical chaotic sequence of simulation tests show that the algorithm has a good multi-step forecast accuracy and better noise immunity)

基于功率谱相减的语音消噪增强法程序，采用软阈值法(Power spectrum subtraction based speech denoising Enhancement Act program, using soft thresholding)

通过matlab实现最大类间方差,根据迭代选择阈值法原理编写.(Through matlab maximum between-class variance, according to the iterative threshold selection method works written.)

关于matlab的入学教程的讲解，很有用的哟！(Tutorial on matlab entry talks, the very useful yo!)

用matlab做的天线转台控制系统，为有扰动情况下并且进行极点配置程序(Using matlab to do the antenna turntable control system for disturbance circumstances and procedures for pole placement)

小波变换和小波包去噪程序，程序清晰，可执行，有注释(Wavelet transform and wavelet packet denoising procedures, procedures are clear, can be implemented, there are notes.)

对小波分析的各种应用和处理，对于许多初学者来说，这有助于他们更好地掌握和应用matlab软件(For the treatment of various wavelet summary)

说明：  局部放电小波去噪，采用db5小波进行5层分解，最后重构信号(Partial discharge wavelet denoising, db5 wavelet is used for 5-level decomposition, and finally the signal is reconstructed)
