Spatial multiplexing with single transmitter on wideband channels

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.
