kernel density estimation MATLAB

OFDM信号在无线通信中会受到多普勒频移的影响，从而影响了OFDM信号的正交性，引起载波间的干扰和OFDM信号符号间的干扰，本代码先形成含有N个二进制码元的信号，而这个信号的前半部分和后半部分的信号是一样的，然后根据把这个信号调制成OFDM信号，最后接收端根据这个OFDM信号估计出多普勒因子(OFDM signal in a wireless communication will be subject to Doppler shift of influence, thus affecting the OFDM signal orthogonality, causing interference and interference between the OFDM signal symbol between carriers, the code first formed comprising N binary symbols signal, and the first and second halves of this signal is the same signal, and then the OFDM signal according to the estimated Doppler factor modulates the signal to the OFDM signal received, the last side)

说明：  车流量检测，需使用matlab computer vision 工具包(Vehicle Flow Detection .Use the MATLAB computer vision Toolkit)

说明：  无刷双馈电机模型，开环仿真总是出错，希望大家帮帮忙看看啊(BDFM model, open-loop simulation is always wrong, hope that we help out and take a look at ah)

Empiricial Mode Decomposition (Hilbert-Huang Transform)

有源电力滤波器(APF:Active power filter)是一种用于动态抑制谐波、补偿无功的新型电力电子装置，它能够对不同大小和频率的谐波进行快速跟踪补偿，之所以称为有源，是相对于无源LC滤波器，只能被动吸收固定频率与大小的谐波而言，APF可以通过采样负载电流并进行各次谐波和无功的分离，控制并主动输出电流的大小、频率和相位，并且快速响应，抵消负载中相应电流，实现了动态跟踪补偿，而且可以既补谐波又补无功和不平衡。(APF:Active power filter))

CFAR即恒虚警检测，是雷达信号处理领域的经典处理算法，其核心是在保证虚警概率一定的条件下，尽可能提高检测概率(CFAR that is constant false alarm detection, radar signal processing field of the classic algorithm, its core is to ensure that the false alarm probability of certain conditions, as far as possible to improve the detection probability)

利用fastICA算法进行复数的独立成份分析，属于盲源分析的一种(fastICA)

这是用Gardner算法做的载波同步，其中用到了扩频系统中的PN序列，程序经过仿真，结果正确(Gardner Symbol synchronization )
