<p>Method and arrangement in a relay node, for cancelling self-interference. The relay node receives wireless input signals. The method comprises receiving an analogue input signal, converting each received analogue input signal into a digital signal, processing the digital signal, extracting a cancellation signal from each respective digitally processed digital signal, filtering the extracted cancellation signals, converting each cancellation signal into an analogue cancellation signal, and subtracting each analogue cancellation signal from the analogue input signal.</p> |
