Pulsar TOA estimation algorithm based on SWT and FRFT
Jinwen Tian · Computer Engineering and Applications Journal · 2008
The pulsar super-resolution TOA algorithm based on stationary wavelet transform and fractional Fourier transform is proposed.First,the pulsar signal in one period is decomposed by multi-SWT.Then,TOA each corresponding to the low frequency part of the FRFT with different resolution is estimated.Finally,multiple-estimation of the pulsar TOA is obtained.The simulation results show that this algorithm can achieve precise and steady TOA with low sampling rate in noisy backgrounds.
