Spectral De-Aliasing Method of Micro-Motion Signals Based on a Complex-Valued U-Net Network

Spectral De-Aliasing Method of Micro-Motion Signals Based on a Complex-Valued U-Net Network

Spectrum aliasing occurs in signal echoes when the sampling frequency does not comply with the Nyquist Sampling Theorem. In this scenario, the extraction of micro-motion parameters becomes challenging. This paper proposes a spectral de-aliasing method for micro-motion signals based on a complex-valu...
