Nonparametric detection of frequency modulated signals using fractional Fourier transform
Shuwen Xu, Peng‐Lang Shui · Electronics Letters · 2010
A detection scheme for unknown nonlinear frequency modulated signals in white Gaussian noise is developed using the fractional Fourier transform and two-dimensional order-statistic filter. The simulation experiment and comparison with other methods available are shown, and the effectiveness of the proposed method is reported.
