Derivation of OTFS Modulation From First Principles [PDF]
IEEE Transactions on Vehicular Technology, 2021 Orthogonal Time Frequency Space (OTFS) modulation has been recently proposed to be robust to channel induced Doppler shift in high mobility wireless communication systems. However, to the best of our knowledge, none of the prior works on OTFS have derived it from first principles. In this paper, using the ZAK representation of time-domain (TD) signals,

Performance Analysis of OTFS Modulation With Receive Antenna Selection [PDF]
IEEE Transactions on Vehicular Technology, 2021 In this paper, we analyze the performance of orthogonal time frequency space (OTFS) modulation with antenna selection at the receiver, where $n_s$ out of $n_r$ receive antennas with maximum channel Frobenius norms in the delay-Doppler (DD) domain are selected.
