Abstract

We have designed an OTFS system with an inherent OFDM modulation accomplished by applying the weighted fractional Fourier transform (WFrFT), that employs the fast Fourier transform (FFT) algorithm, unlike DFrFT, to bring down the complexity. The system’s bit-error rate (BER) is comparable to the DFrFT-OFDM-based OTFS system, having a dB gain over the standard OTFS system with the same complexity and PAPR
