SELF-INTERFERENCE SUPPRESSION CONTROL FOR A RELAY NODE |
摘要 |
A technique for self-interference suppression control for a relay node is provided. The relay node comprises a transmitter and a receiver, and is adapted to transmit and received simultaneously using the same frequency channel or using proximate frequency channels. The relay node further comprises an interference signal estimator having a first input adapted to receive a transmitter signal from the transmitter, a second input adapted to receive adaptation metric and an output adapted to output an estimated interference signal generated by the interference signal estimator based on the transmitter signal and the adaptation metric. A subtractor is coupled to the output of interference signal estimator and configured to subtract the estimated interference signal from a received signal in the receiver so as to actively cancel a signal transmitted from the relay node that leaks back into the receiver of the relay node to suppress self-interference. |
