Delay-Doppler-Domain Channel Estimation and Reduced-Complexity Detection of Faster-Than-Nyquist Signaling Aided OTFS

This paper introduces an innovative delay-Doppler-domain channel estimation scheme and a reduced-complexity detector designed specifically for Faster-Than-Nyquist (FTN) signaling-aided OTFS systems.

Precoded Faster-Than-Nyquist Signaling Using Optimal Power Allocation for OTFS

In this work, we present a power-allocated precoded Faster-Than-Nyquist (FTN) signaling scheme for Orthogonal Time Frequency Space (OTFS) systems.

Reduced-Complexity MIMO Faster-Than-Nyquist Signaling Transceiver for OTFS Modulation

We design a reduced-complexity Multiple-Input Multiple-Output (MIMO) Faster-Than-Nyquist (FTN) transceiver architecture for Orthogonal Time Frequency Space (OTFS) systems.
