Delay Doppler Transform

Published 9 Nov 2023 in eess.SP | (2311.05236v2)

Abstract: This letter is to introduce delay Doppler transform (DDT) for a time domain signal. It is motivated by the recent studies in wireless communications over delay Doppler channels that have both time and Doppler spreads, such as, satellite communication channels. We present some simple properties of DDT as well. The DDT study may provide insights of delay Doppler channels.
