用Matlab语言实现通信系统的后处理功能(Language communication system using Matlab post-processing functions)

说明：  matlab谱分析实例，即通过matlab仿真信号的频谱过程。(spectral analysis matlab example, matlab simulation of signal through the course of the spectrum.)

使用鏡子鏡射的原理，也就是將接收點鏡射之後，求取傳送點與接收點的距 離，而因為公式(1)及公式(8)，可知角度與距離有關係，可以使用這個公式來直 接代入公式(10)之中。(. The receiver is located at the center of a 50-m*50-m room and transmitter is moved along a straight from 2m to 20m from the receiver. Show the received power in decibels versus distance for the LOS path, and include all the first-, second-,third-order reflections. (Gt = Gr = 1.6, f = 1GHz, a =-0.7, Pt = 1W))

用于进行MNF变换，mnf用于对高维数据进行降维，特征提取(For MNF transformation, MNF is used for dimensionality reduction and feature extraction of high-dimensional data.)

用间类最大距离法自动求取多张图像的阈值，MATLAB实现(With the largest distance between the type of multiple images automatically strike the threshold, MATLAB realize)

vector control permanent magnetmotor

噪声幅度调制信号仿真代码（使用的是高斯白噪声）(Noise amplitude modulation signal simulation code (using a Gaussian white noise))

一个老外写的文章，很不错，对以后学习核主元分析（KPCA）有帮助！(the paper was written by the foreigner，which is very useful and meaningful.)

在永磁同步电机的运动控制系统中采用直接转矩控制策略，其性能的优劣程度取决于磁链和电磁转矩的控制情况，因此很有必要进一步的研究控制系统转矩和磁链的性能。(Permanent magnet synchronous motor is widely used in the field of speed control systems because of its various high performance,such as its small volume, high efficiency, reliable work performance, and the advantage of being able to adapt to harsh environment.Direct torque control technology regards the induction motor as the research object , because its idea is novel , its architecture is simple and it has excellent static and dynamic performance of the system , so this technology has received extensive attention.This paper focuses on the surface mounted permanent magnet synchronous motor, and the main work is as follows at direct torque control system.)
