Improved Denoising Method for UWB Vital Signs Detection and Extraction

In order to remove the interference of background noise and extract the vital signs smoothly, an improved denoising method based on SVD-EEMD for UWB vital signs detection and extraction is proposed in this paper. The SVD method is used to decompositing preprocessed echo signal matrix, and the characteristics of life signals is extracted by the EEMD method, which is especially suitable for life detection carried on UWB Radar.
