While rapid variations of the fading channel cause intercarrier interference (ICI) in OFDM,
thereby degrading its performance considerably, they also introduce temporal diversity …

In orthogonal frequency-division multiplexing, time variations of a multipath channel lead to
a loss of orthogonality between the subcarriers, and thereby limit the achievable throughput …

In this work, we derive a equivalent delay-Doppler channel matrix of the Orthogonal Time
Frequency Space (OTFS) modulation that has not been studied in previous literature. It has …
