Patent ID: 8761681

Claim:
A device for reducing an error signal component of a transmit signal in a receive signal, comprising: an interface configured to obtain a narrow-band payload signal; a transmit signal generator configured to generate a transmit signal having a known wideband error signal component based on the narrow-band payload signal; a transmitting/receiving device configured to transmit the transmit signal at a transmit frequency and receive the receive signal at a receive frequency, wherein a proportion of the known wideband error signal component of the transmit signal being superimposed on the receive signal; a correction signal generator configured to generate a correction signal based on the known wideband error signal component of the transmit signal or a signal derived therefrom; and a combiner configured to combine the receive signal with the correction signal in order to reduce in the receive signal the proportion that is based on the known wideband error signal component of the transmit signal.
