Abstract

A transmitter is configured to transmit at least one signal with a pilot sequence having a plurality of pilot symbols, wherein the transmitter has a signal generator, wherein the signal generator provides the pilot sequence, wherein the signal generator provides the pilot sequence such that the pilot sequence has at least two symbol groups each having at least two pilot symbols, and the symbol groups, when evaluating a signal received by a receiver as a result of the transmission of the signal with respect to a phase, the symbol groups generate phase errors that depend on a temporal off-set between a reference point in time of the transmission of the signal by the transmitter and a value assumed and/or estimated for the evaluation for the reference point in time, said phase errors essentially mutually compensating each other across the symbol groups in the evaluation.
