Abstract

Embodiments provide a data receiver with a unit for receiving sub-data packets configured to receive at least two sub-data packets from a data transmitter, and to combine the at least two sub-data packets to obtain a data packet that is transmitted split into the at least two sub-data packets by the data transmitter, wherein each of the at least two sub-data packets is shorter than the data packet, a unit for receiving sub-data packets configured to receive the at least two sub-data packets on at least two different carrier frequencies a unit for determining a phase difference configured to determine a phase difference between the at least two sub-data packets that is caused by the at least two different carrier frequencies and the path delay, and a unit for determining a distance difference configured to determine a distance difference between the data receiver and the data transmitter based on the determined phase difference between the at least two sub-data packets.
