中文说明：FIR 底通和带通滤波器和IIR 底通和带通滤波器，计算加权加速度,采用加权网络中节点强度和权重都是幂率分布的模型，包括广义互相关函数GCC时延估计，数学方法是部分子空间法，有借鉴意义哦。
English Description：
At the bottom of the fir pass and band-pass filter and IIR bottom pass and band-pass filter, calculation of the weighted acceleration, the weighted network node strength and weight are power-law distribution model, including generalized cross correlation GCC function for time delay estimation, the mathematical method is part of the sub space method, the reference oh.
