Noise Frequency Modulation Interference Suppression and Interest Signal Separation

Multi-component signal separation under strong interference has been a concern. This study aimed to investigate an effective signal separation algorithm. Interference suppression is first performed using the logarithmic cancellation method. The successive variational mode decomposition algorithm was designed and constructed, which is derived from Variational Mode Decomposition and can be regarded as an optimized Variational Mode Decomposition. Numerical simulation results show that performing multi-component signal separation with the successive variational mode decomposition method after logarithmic cancellation has superior performance.
