摘要: In this paper, a method of estimating the power spectrum complex signal based on Group Delay function (GD) is proposed and also applied to Wigner-Ville Distribution (WVD) reduce ripple effect due truncation autocorrelation sequence. The realised by GD for modified concept. This extends performance advantages applicable real signal, one. Further, its application WVD, reduces truncation/ripple without sacrificing any frequency resolution, as nocommon window used. Significant improvement in performance, terms reduction variance compromise resolution higher noise immunity, has been found over those periodogram windowed WVD.
