Performance evaluation of multi-component instantaneous frequency estimation techniques for heart rate variability analysis
(2012 , Conference Paper)
Accurate instantaneous frequency (IF) estimation of the non-stationary heart rate signal is important in quantifying the heart rate variability (HRV) measures. This study compares the effectiveness of four IF estimation ...
A cross-terms geometry based method for components instantaneous frequency estimation using the Cross Wigner-Ville distribution
(2012 , Conference Paper)
A novel method for the signal components instantaneous frequency (IF) estimation based on the CrossWigner-Ville distribution (XWVD) is presented. The cross-terms in the XWVD are deliberately formed between the analyzed ...
