Stochastic modeling and simulation of ground motions using complex discrete wavelet transform and Gaussian mixture model

The block diagram of the proposed model is shown in following figure. It is divided into three parts: the first part refers to modeling of the target ground motion using the complex discrete wavelet transform (CDWT) and the Gaussian mixture (GM) distribution; the second part refers to the generation of synthetic ground motion using the fitted GM distributions; and the third part refers to the comparison of synthetic and real ground motions to validate the proposed model.158
