Fractional Fourier Transform Receiver for Modulated Chirp Waveforms

Phase-Coded FMCW for Coherent MIMO Radar

“…Performing the filter bank receiver approach causes the computational complexity of discrete Fourier transform (DFT) O(N 2 ). A more efficient implementation via fractional Fourier transform has been recently proposed, hence being still more costly than the group delay filter receiver [34], [35].…”
