Abstract
Systems, methods, and devices detect variations in load impedances of wireless communications devices. Methods include determining a first distortion measurement of a transceiver based on a first comparison of a digital loopback path and a radio frequency (RF) loopback path, and determining a second distortion measurement of the transceiver based on a second comparison of the digital loopback path and the RF loopback path. Methods also include implementing, using a processor, a third comparison of the first distortion measurement and the second distortion measurement, and determining if there is a change in a load of the transceiver based on the third comparison.
