    摘要: Aspects of the subject disclosure may include, for example, obtaining data regarding interference originating from one or more interference sources, and electronically rotating polarizations of signals relating to crossed-dipole radiating elements of an antenna system, the antenna system operating in multiple frequency bands, the electronically rotating being performed for a select number of frequency bands of the multiple frequency bands and facilitating mitigation of the interference. Other embodiments are disclosed.

    摘要: A system that incorporates aspects of the subject disclosure may perform operations including, for example, receiving an uplink signal generated by a communication device; generating an estimation of one or more downlink signals generated by one or more transmitters; detecting a passive intermodulation interference in the uplink signal, wherein the passive intermodulation interference is caused by the one or more transmitters, wherein the passive intermodulation interference is detected by the circuit based on a comparison of characteristics of the uplink signal with the estimation of the one or more downlink signals generated by the one or more transmitters, and wherein the one or more transmitters are unassociated with the communication device generating the uplink signal; and performing signal conditioning on the uplink signal to reduce the passive intermodulation interference. Other embodiments are disclosed.

    摘要: A system that incorporates aspects of the subject disclosure may perform operations including, for example, receiving, via an antenna, a signal generated by a communication device, detecting an interference in the signal, the interference generated by one or more transmitters unassociated with the communication device, and the interference determined from signal characteristics associated with a signaling protocol used by the one or more transmitters, and performing signal conditioning on the signal to reduce the interference. Other embodiments are disclosed.
