用实验方法测试RLC串联谐振电路的幅频特性曲线。当正弦交流信号的频率f改变时，电路的感抗、容抗随之而变.取电路电压U0作为响应，当输入电压Ui幅值维持不变时，在不同信号频率的激励下，测出U0之值，用LabVIEW程序完成频谱分析和滤波，变换等信号处理，即可测出RLC串联电路的谐振频率，(Amplitude-frequency characteristics experimentally tested RLC series resonant circuit curve. When changing the frequency f of the sinusoidal AC signal, the circuit inductance, capacitance change with Take circuit voltage U0 as a response when the amplitude of the input voltage Ui unchanged, signals at different excitation frequencies, the measured value U0, the process is complete spectrum analysis using LabVIEW and filtering, transform signal processing, can be measured RLC series circuit resonant frequency,)

该编程源代码主要介绍了一种密度峰值聚类的方法(This programming source code mainly introduces a method of density peak clustering.)

This package implements basic Principal Component Analysis and Eigen Faces in Matlab and tests is with grayscale portion of the FERET database. Images are not preprocessed and it is up to the user to preprocess the images as wanted, not changing the filenames.

基于CP的最大似然估计仿真图，两幅图，分别是符号定时偏差，以及频偏，从图中可以看出在符号定时估计最大处，相应的频偏估计值也是最接近的(CP-based maximum likelihood estimate simulation map, two maps, are a symbol timing offset, and frequency offset, it can be seen the figure in the symbol timing estimation is maximum, the corresponding value is also the closest frequency estimation)
