电气化铁路接触网过分相过电压的matlab仿真研究，对于掌握并治理过电压具有积极的作用(Simulation study of MATLAB electrified railway contact net over phase overvoltage, plays a positive role in control and governance over voltage )

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用周期图法和 ARMA谱估计法(SVD-TLS)估计此信号的功率 谱，并分析比较其结果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try periodogram and ARMA spectral estimation method (SVD-TLS) estimate the power spectrum of this signal, and the analysis and comparison of the results)

DRAM算法，是一种改进型的蒙特卡罗马尔科夫链（MCMC）采样方法，该算法基于经典的MCMC算法，在此基础上增加了改进策略，是算法能够更快速稳定的收敛。(DRAM algorithm is an improved Mirkov chain (MCMC) sampling method, the algorithm is based on the classic MCMC algorithm, based on the increase in the improvement of this strategy is the algorithm to more rapid and stable convergence.)
