Aspects of the subject disclosure may include, for example, receiving, via an antenna, a communication signal generated by a communication device, and detecting interference in the communication signal, wherein the interference is generated by one or more interference sources, wherein the interference is detected by monitoring a near field region of the antenna, an intermediate field region of the antenna, a far field region of the antenna, or any combinations thereof, wherein the monitoring excludes monitoring only the far field region of the antenna. Other embodiments are disclosed.

Aspects of the subject disclosure may include, for example, identifying one or more radiating elements of an antenna system that are to be adjusted based on interference determined to affect an operation of the antenna system, and altering one or more properties of the one or more radiating elements to effect polarization adjusting such that an impact of the interference on the antenna system is minimized. Other embodiments are disclosed.

Aspects of the subject disclosure may include, for example, obtaining data regarding passive intermodulation (PIM) detected in a received communication signal, and performing polarization adjusting for a communications system such that an impact of the PIM on the communications system is minimized. Other embodiments are disclosed.

Aspects of the subject disclosure may include, for example, performing, by an adjusting mechanism associated with a communications system, polarization adjusting for an uplink of the communications system, and performing, by the adjusting mechanism, polarization adjusting for a downlink of the communications system, wherein a first polarization of the uplink and a second polarization of the downlink are different. Other embodiments are disclosed.

Provided is a method (300) and a successive interference cancellation (SIC) based multi-user uplink receiver (200) for multi-user uplink transmission. The method comprises receiving (302) signal of one or more multiple-access (MA) scheme waveforms by a plurality of antennas (202.1, . . . , 202.R) from one or more users. The method further comprises determining (304) one or more effective channel matrices corresponding to the plurality of antennas. Thereby, the method comprises performing (306) channel equalization for signal received in a corresponding antenna by an effective channel matrix. Furthermore, the method comprises combining (308) the channel equalized signal. Subsequently, the method comprises detecting (310) Correctly Decoded Code Blocks (CCBs) and Wrongly Decoded Code Blocks (WCBs). Upon detecting CCBs and WCBs, the method comprises performing (312) the SIC on received signals from one or more users until all WCBs are converted to CCBs or a maximum number of threshold iterations are completed.
