《MATLAB程序设计教程》电子教案～～～有助于matlab学习(" MATLAB Programming Guide" e-lesson plans ~ ~ ~ help matlab learning)

关于matlab学习的PPT，里面介绍了matlab的一些基本知识，对于初学者非常有用。(PPT on matlab learning, which introduced some basic knowledge of matlab is very useful for beginners. )

此程序能将一个信号进行EMD分解，已近调试过，绝对没问题，主程序为emd1.m，用户可以随意更改里面的信号函数Xn。(This program converts a signal with EMD nearly debugged, absolutely no problem, main program for emd1.m, the user can freely change inside the signal function Xn.)

使用对称秩1算法求解无约束问题 输入包括初始点，目标函数和梯度 输出包括最优点最优解和迭代次数(Rank 1 using symmetric algorithms for unconstrained problems including initial entry points, the objective function and the gradient of the output, including the most optimal solution and the advantages of iterations)

发送装置：随机信号产生、脉冲成型（上采样可调，滚降可调）； 发送：AWGN信道（信噪比范围可调） 接收设备：QPSK调制解调 ，匹配滤波，判决 画出接收信号的眼图、星座图；计算误码率并与理论值比较。 (Transmitting device: random signal generator, pulse shaping (the sampling adjustable, adjustable roll-off) Send: AWGN channel (SNR range is adjustable) Receiving equipment: QPSK modulation and demodulation, matched filtering, judgment   BER is calculated and compared with the theoretical value draw the received signal eye diagram, constellation.)

用MATLAB设计各种滤波器参数，包括各种窗函数法，如凯撒、汉明、布莱克特等(MATLAB filter design using a variety of parameters, including a variety of window function, such as Kaiser, Hamming, Blackett, etc.)
