Abstract :
The authors use a wavelet transform to build a simulated model of an HRV signal and to create an algorithm for HRV signal decomposition. They review the characteristics of HRV signals and discuss an improved integral pulse frequency modulation model for the simulation of these signals. They also present results that show how their model approximates a real HRV signal.
