Self-interference cancellation in full-duplex wireless devices: A survey
2019
Full-duplex wireless nodes can transmit and receive at the same time and in the same frequency band, thus effectively doubling the data rate. In these systems, the transmit signal interferes with the receive signal, a phenomena termed as self-interference. Self-interference is a major impediment to realising a full-duplex wireless node. In the recent years, there has been significant research on self-interference mitigation. In this paper, we survey important techniques for self-interference cancellation from the past few years. In particular, we focus on the various RF and baseband self-interference cancellation techniques for realising an ideal full-duplex node.
