电子工业出版社 《数字信号处理》第2版课后题MATLAB 3-4 3-8 3-14 3-22题(Electronic Industry Press Digital Signal Processing 2nd edition title after title MATLAB 3-4 3-8 3-14 3-22)

自己实现的，模糊C均值聚类的代码，在K-mean上添加了隶属度矩阵。注释详细，方便理解算法步骤(my implementation, Fuzzy C-Means clustering code in the K-mean adding a membership matrix. Notes detailed, easy to understand algorithm steps)

逆变器具有灵活、高效的特点，是新能源并网的主要接口。当多个逆变器连接到电网的同一个公共连接点时，逆变器非理想的电源特性，使得逆变器之间、逆变器与电网之间存在的谐波交互作用可能引发谐振， 使系统出现过电压、 过电流现象影响电网的电能质量，甚至威胁系统的安全稳定运行(Inverter is flexible and efficient, and it is the main interface of new energy integration. When multiple inverters are connected to the same common connection point of the power grid, the inverter is not ideal. The harmonic interaction between the inverters, the inverter and the grid may cause resonance, which causes the overvoltage and overcurrent to affect the power quality of the power grid and even threatens the safety of the system. stable operation)

使用qam星座调制方式下的，空时编码STBC的误码率(BER)仿真(The use of QAM modulation constellation manner, the space-time coding STBC BER (BER) simulation)

Matlab有关改进的PSO算法程序基于三种惯性参数改进的粒子群算法程序,并使用测试函数Goldstein进行结果比较(Matlab program for improving the PSO algorithm is based on three inertial parameters improved particle swarm optimization program and use the results of the test functions were compared Goldstein)

说明：  使用Matlab生成M序列，自己设置初值及本原多项式，并分析(Matlab generates M sequence)

基于稀疏表示的正交最小二乘法，使用的语言是matlab，应用比较广阔，设计信号处理中的信号回归，图像处理的压缩等。(Sparse representation based on orthogonal least squares method, the language used is matlab, relatively broad application, design signal processing signal return, image processing, compression and so on.)

FFT 实例 x=0.5*sin(2*pi*15*t)+2*sin(2*pi*40*t)。采样频率fs=100Hz，分别绘制N=128、1024点幅频图(FFT in Matlab example)

说明：  使用matlab来提取nastran生成的pch文件中的刚度矩阵与质量矩阵(Extraction of stiffness matrix and mass matrix)

说明：  调制宽带转换器仿真源代码，基于压缩感知理论，对多带信号进行压缩、和重构(Modulated wideband converter simulation source code)
