周期图法谱估计需要对信号序列“截断”或加窗处理,其结果是使估计功率谱密度为信号序列真实谱和窗谱的卷积,导致误差的产生。本程序分别设计了周期图法,最大熵功率谱估计和Welch法以及它们的对比,最大熵功率谱估计目的是最大限度地保留截断后丢失的“窗口”以外信号的信息,使估计谱的熵最大。(Periodogram spectrum estimation signal sequence needs to " cut off" or add the window handle, the result is an estimated power spectral density of the signal sequence of the real spectrum and spectral convolution window, resulting in the generation of errors. The procedures were designed periodogram, maximum entropy power spectrum estimation and the Welch method and their comparison, the maximum entropy power spectrum estimation purpose is to maximize the retention of truncated after the loss of the " window" than the information signal, the entropy of the estimated spectrum maximum.)

prony 工具箱(in matlab)
prony工具箱用于对信号进行prony分析,(We have designed a software tool in MATLAB, the Prony Toolbox, to perform Prony analysis. Prony Toolbox (PTbox) is designed based on several considerations including data preprocessing, model order selection, model order selection criteria, signal subspace selection, signal and noise separation, root inspection and assessing residuals. The PTbox provides flexibility to compare and display analysis results simultaneously for several parameter variations.)

subtightplot
subtightplot is a merger of Pekka Kumpulainen s tight_subplot and Nikolay S. s subplot_tight. It extends the former, which supports asymmetric subplots, to allow for variable margins in addition to gaps, as in the latter.
