Claim:
1. A wireless communication interface for an electronic device, comprising: a baseband encoder that encodes a transmit digital baseband signal; a transmitter that transmits the encoded transmit digital baseband signal as a corresponding transmit radio frequency signal via an antenna assembly of the electronic device on an uplink band; a receiver that receives radio frequency signals on each of a first downlink band and a second downlink band via the antenna assembly and generates corresponding encoded receive digital baseband signals for the first and second downlink bands; an interference cancelling unit that subjects fewer than all downlink bands to interference cancelling by generating a correction signal from the encoded transmit digital baseband signal, and subtracting the correction signal from the encoded receive digital baseband signal corresponding to the first downlink band and not from the encoded receive digital baseband signal corresponding to the second downlink band, outputs of the interference cancelling unit comprising an interference corrected version of the encoded receive digital baseband signal corresponding to the first downlink and an unmodified version of the encoded receive digital baseband signal corresponding to the second downlink band; and a baseband decoder that decodes the interference corrected version of the encoded receive digital baseband signal corresponding to the first downlink and the encoded receive digital baseband signal corresponding to the second downlink band.
