Research on the Separation Method of LFM Signal Based on VMD-FastICA
2021 World Conference on Computing and Communication Technologies (WCCCT)(2021)
摘要
In order to solve the problem of single-channel separation of LFM signals, a method based on variational mode decomposition (VMD) and fast independent component analysis (FastICA) is proposed to separate signals. Firstly, we set the secondary penalty factor required by VMD and the number of signals. Secondly, the modal component signals are obtained by VMD. Finally, the FastICA separation algorith...
