The minimality of mean square error in chirp approximation using fractional fourier series and fractional fourier transform
Abstract Chirps are familiar in nature, have a built-in resistance to noise and interference, and are connected to a wide range of highly oscillatory processes. Detecting chirp oscillating patterns by traditional Fourier series is challenging because the chirp frequencies constantly change over time...
