Original Abstract Submitted
An apparatus is disclosed that implements interference and/or clutter cancellation using cross-channel equalization. In example aspects, the apparatus includes a wireless transceiver configured to be connected to multiple feed ports. The wireless transceiver is also configured to transmit an electromagnetic signal using a first feed port of the multiple feed ports. A modulated spur is generated based on the transmission of the electromagnetic signal. The wireless transceiver is additionally configured to receive two versions of a receive signal respectively via two feed ports of the multiple feed ports. The receive signal comprises the modulated spur and a mutual-coupling component associated with the transmission of the electromagnetic signal. The wireless transceiver is further configured to generate a filtered signal by attenuating the mutual-coupling component and the modulated spur within one of the two versions of the receive signal using cross-channel equalization.
