通过对各种窗函数的matlab仿真，比较各种窗函数的频谱特性，并且将不同的窗函数加权到脉压信号上，观察特性的优劣-Based on all kinds of window function of matlab simulation, compare all kinds of window function, the characteristic of the frequency spectrum of and different window function weighting to the

Parzen窗估计法是一种非参数函数估计方法，它能够较好地描述多维数据的分布状态。其基本思想就是利用一定范围内各点密度的平均值对总体密度函数进行估计。-Parzen window estimation method is a nonparametric function estimation method, which can describe the distribution of multi-dimensional data. The basic idea is to use the ave
