a good simulink model of Space Vector PWM

基于matlab/simulink搭建的三电平逆变器仿真模型，控制算法为电压空间矢量控制（SVPWM），算法部分使用m语言编写，带有简单注释，配合算法说明，应该比较好懂。模型带中点电压平衡处理，但是效果一般，大家可以在此模型基础上修改。欢迎交流讨论。(Three-level inverter simulation model matlab/simulink structures based control algorithms for the voltage space vector control (SVPWM), part of the algorithm using the m language, with a simple comment, with the algorithm description, it should be relatively easy to understand. Models with the midpoint voltage balanced, but the general effect, you can modify the model basis. Welcome exchanges and discussions.)

Feature Extraction using matlab

模拟2个独立窄带信号入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵列的阵元数为10，快拍数为200。阵元间距为入射信号波长的1／2，信噪比为20dB，信号入射角度差分别为5°，10°，20°。(Simulate two independent narrowband signals incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the number of array elements of the array is 10, the number of snapshots to 200. Element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB, the signal difference between the angle of incidence was 5 °, 10 °, 20 °.)

根据干扰信号波形样式的不同，压制性干扰可分为噪声调幅干扰、噪声调频干扰、噪声调相干扰。就是用噪声或类似噪声的干扰信号遮盖或淹没有用信号，阻止雷达检测目标信息。它的基本原理是：任何一部雷达都有外部噪声和内部噪声，雷达对目标的检测是在这些噪声中进行的，其检测又是基于一定的概率准则的。一般来说，如果目标信号能量S与噪声能量N相比（信噪比S/N），超过检测门限D，则可以保证一定的虚警概率Pfa的条件下达到可检测目标回波所要求的检测概率Pd，简称为可发现目标，否则便称为不可发现目标。(Blanket Jamming can be divided into different styles according to the interference signal waveform, noise AM interference, noise FM jamming noise phase modulation interference. With noise or noise-like interference signal covered or submerged useful signal prevent radar detection target information from. Its basic principle is: any one radar has the external noise and the internal noise of the radar target detection in these noise detection is based on a certain probability criterion. Generally, compared to if the target signal energy S and noise energy N (signal-to-noise ratio S/N), more than the detection threshold D, you can guarantee reach target echo can be detected under the conditions of a certain false alarm probability Pfa requirements detection probability Pd, referred to can be found in the target, otherwise known as not finding the target.)

说明：  SCA算法实现，主要针对凸优化问题进行求解，可以在其他地方使用。(SCA algorithm, mainly for convex optimization problems, can be used in other places.)
