1. An apparatus for wireless communication at a user equipment (UE), comprising:
a processor;
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
measure a plurality of pulses of a signal, wherein the plurality of pulses comprises a first set of pulses resulting from first power supplied to a first cable for transmissions from a first antenna of a plurality of antennas of the UE operating in a transmit diversity mode and a second set of pulses resulting from power leakage into the first first cable, wherein the power leakage into the first cable results from an electrical component supplying second power to a second cable for transmissions from a second antenna of the plurality of antennas;
apply a leakage detection function to the plurality of pulses to filter out the second set of pulses from the first set of pulses; and
perform an antenna compensation operation based at least in part on applying the leakage detection function.
