Cross-term Reduction Using Wigner Hough Transform and Back Estimation

Abstract

This paper presents some algorithms to reduce the cross-terms, which are unfortunate mathematical artifacts in the calculation of Wigner Ville Distribution (WVD) of a multi-component signal. The experiments are carried out for linear FM signals which have a line representation in the spectral domain. When the WVD of a multi-component signal is calculated… (More)
