LEAKAGE CANCELLATION A MULTIPLE-INPUT MULTIPLE-OUTPUT TRANSCEIVER

摘要

A transceiver 100 for simultaneous transmission and reception of communication signals in a multiple-input multiple-output, MIMO, system allowing operation on at least partly overlapping frequency bands. The transceiver 100 comprising an antenna arrangement 110, a duplex arrangement 120, and a modem unit 130. The duplex arrangement 120 being adapted to forward a transmit signal T1 from the modem unit to the antenna arrangement 110. The duplex arrangement 120 also being adapted to receive a receive signal R1 from the antenna arrangement 110 and to forward an interference suppressed receive signal R2 to the modem unit. The duplex arrangement 120 comprising an interference cancellation unit adapted to generate the interference suppressed receive signal R2 by combining the receive signal R1 from the antenna arrangement and the transmit signal T1.
