摘要：
A wavelet transform is used to build a simulated model of a heart rate variability (HRV) signal and to create an algorithm for HRV signal decomposition. The HRV signals simulated by this model include harmonic components and a 1/f component. The model can create simulated HRV signals that approximate the real HRV signal, both in time and frequency domain. An HRV signal is decomposed into the 1/f component and non-1/f component. A decomposition algorithm based on the wavelet transform is used to process the effects of +Gz in a test to select high-performance fighter pilots.
