说明：  基于16QAM调制解调的OFDM信道估计，计算了不同信噪比下的误码性能曲线，并画出了图。(Comb based on the OFDM pilot channel estimation, calculation of the BER performance under different signal to noise ratio curve, and draw the map.)

电力电子电路 三相半波可控整流电路simulink仿真(Power electronic circuit of three phase half wave controllable rectifier circuit with Simulink simulation)

说明：  MATLAB SIMULINK仿真程序，主要实现光伏电池及其最大功率点跟踪。(Matlab Simulink simulation program, mainly to achieve photovoltaic cells and their maximum power point tracking.)

PCA算法。PCA的目的是找到能够分离出最大方差的方向，所以首先求原来所有数据三个维度上的协方差，然后求这个协方差的特征值，最大特征值为第一个方向，从此以此类推。(PCA algorithm. The purpose of PCA is to find able to isolate the direction of maximum variance, so first find all the data in three dimensions on the original covariance, and then find the eigenvalues ​ ​ of the covariance, the biggest feature is the first in one direction, from and so on.)

This a simple demonstration of a content based image retri using 2 techniques. 1. Using knn for image retri 2. Using svm for image retri .
