WebThis paper proposes a new signal decomposition method that aims to decompose a multicomponent signal into monocomponent signal. The main procedure is to extract the components with frequencies higher than a given bisecting frequency by three steps: (1) the generalized demodulation is used to project the components with lower frequencies … WebIt can be seen that the CNN model optimized by wavelet transform has a strong generalization ability, and the deep features of the whole original signal can be obtained through less sample learning. ...
