Low Complexity Channel Estimation for OTFS Modulation with Fractional Delay and Doppler
Imran Ali Khan, Saif Khan Mohammed
We consider the problem of accurate channel estimation for OTFS based systems with few transmit/receive antennas, where additional sparsity due to large number of antennas is not a…

Spectral Efficiency of OTFS Based Orthogonal Multiple Access with Rectangular Pulses
Venkatesh Khammammetti, Saif Khan Mohammed
In this paper we consider Orthogonal Time Frequency Space (OTFS) modulation based multiple-access (MA). We specifically consider Orthogonal MA methods (OMA) where the user terminal…
