1. A device comprising:
a transceiver circuit, wherein the transceiver circuit is arranged to transmit a signal to a receiver; and
a precoder circuit,
wherein the precoder circuit is arranged to acquire a first data signal and a second data signal,
wherein the precoder circuit is arranged to perform a first multipath-precoding of the first data signal according to a first plurality of paths so as to acquire a first precoded signal,
wherein the first plurality of paths are between the device and the receiver,
wherein the precoder circuit is arranged to perform a second multipath-precoding of the second data signal according to a second plurality of paths so as to acquire a second precoded signal,
wherein the second plurality of paths are between the device and the receiver,
wherein the precoder circuit is arranged to generate the first precoded signal and the second precoded signal,
wherein the second precoded signal has an offset with respect to the first precoded signal,
wherein the offset comprises at least one of a time delay and a frequency shift,
wherein the device is arranged to transmit the first precoded signal and the second precoded signal to the receiver via the transceiver circuit, and
wherein the transmission of the first precoded signal and the second precoded signal has a radiation characteristic of the transceiver circuit.
