TRANSMIT DIVERSITY POWER LEAKAGE DETECTION AND FILTERING IN ANTENNA COMPENSATOR POWER DETECTOR

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may filter leaked power from a signal to accurately perform antenna compensation operations (e.g., apply a transmit gain, perform cable loss measurements) using valid power. A switch at the UE may leak power to an antenna for a transmission, and the UE may use a dynamic filtering algorithm to determine whether a pulse power of a detected signal is leaked or valid. The dynamic filtering algorithm may be able to account for variations in leaked power values, as leaked power may increase or decrease proportionally to intended power (e.g., from which power was leaked). By determining whether pulse power is leaked or valid, the UE may be able to filter out the leaked power and accurately perform antenna compensation operations such as applying a transmit gain for a transmission, performing a cable loss measurement, or the like.
