Abstract

We have designed an OTFS system withan inherent OFDM modulation accomplished by applying theweighted fractional Fourier transform (WFrFT), that employsthe fast Fourier transform (FFT) algorithm, unlike DFrFT, tobring down the complexity. The system’s bit-error rate (BER) iscomparable to the DFrFT-OFDM-based OTFS system, having adB gain over the standard OTFS system with the same complexity and PAPR
