摘要：A wireless communication device includes a core logic, first and secondtransceiver chains, first and second antennas, and an interference processor. The corelogic is coupled to both the first and second transceiver chains, which in turn are coupledto the first and second antennas, respectively. The interference processor is coupledbetween the first and second transceiver chains. To calibrate circuitry within the firsttransceiver chain using first signals generated in the first transceiver chain while thesecond transceiver chain is transmitting second signals via the second antenna, theinterference processor connects the transmit circuit of the second transceiver chain tothe receive circuitry of the first transceiver chain to form an interference feedback paththat can be used to compensate for unwanted components of the second signalundesirably picked up by the first antenna.
