A method for adaptive transmitter symbol arrangement in delay-Doppler domain grids including retrieving one or more current communication relevant parameters; deriving from the one or more current communication relevant parameters at least a maximum expected Doppler frequency shift for a transmitted signal; placing at least one pilot symbol in a delay-Doppler domain grid; placing a minimum number of guard symbols around the at least one pilot symbol in the delay-Doppler domain grid so the guard symbols occupy a guard space around the at least one pilot so any grid position outside the guard space around the at least one pilot has a distance along the first grid direction exceeding the derived first guard space parameter and also has a distance along the second grid direction that exceeds the second guard space parameter; and placing data symbols in the delay-Doppler domain grid outside the guard space for data transmission.
