Vision based pedestrian detection system based on pso

LFM信号，通过IQ解调，再A/D变换，上变频，分析输出信号频谱(LFM signal, through the IQ demodulation, and then A/D conversion, on the frequency, the output signal spectrum analysis)

这是一个实现预失真功能的算法仿真，效果不错，希望对大家有所帮助。(a algorithm of predistortion is proposed in this program，and it has a good performance，)

有限差分法(finite difference method ... ... ... ... ... ... ... ... ... ... )

对轴承振动信号进行各种时频分析，以获取相应的时频域分布图，用于轴承故障诊断(bearing vibration signal time-frequency analysis to obtain the corresponding time-frequency domain distribution for bearing fault diagnosis )

三相背靠背交流直流交流simulink仿真模型，采用PWM调制，电压闭环控制(VSC1 controls DC link voltage (Vdc 680 V)and VSC power factor on 60 Hz grid (PF 1.0)PWM frequency 33*60 1980 Hz VSC2 controls load voltage (VLL 380 Vrms 50 Hz) PWM frequency 2000 Hz )

说明：  光伏电池最大功率点的模糊控制算法（Fuzzy）(Fuzzy Algorithms for Controlling the Maximum Power Point of Photovoltaic Cells)

siftdemo原码（MATLAB），SURF是C++文件，检测可以使用。(siftdemo original code (MATLAB), SURF is a C++ file。they can be used 。)

比较不同约束长度下和不同回溯深度下的卷积码性能(Convolutional codes Performance comparison of different constraint lengths and different depths of backtracking)

说明：  信号经过滤波器，会发生相移，本程序设计了零相位滤波器，矫正相位(The signal passes through the filter, will occur the phase shift, this procedure designs the zero phase filter, corrects the phase)
