Abstract
An error correction component and ΔTΘM function determine correction factors from a feedback signal to use by digital predistortion to cancel distortion caused by a power amplifier and also determine correction factors that may be used to determine Time of Arrival of an isolation leakage signal. Correction factors may be stored in, or retrieved from, multiple ΔTΘM functions, which may be part of an ASIC along with the error correction component. The isolation leakage signal may be canceled within the error correction component, resulting in a leakage residual signal that may facilitate determining the ToA of the leakage signal. Cancelling the isolation leakage signal facilitates better sensitivity in detecting the presence of, or ToA of, other signals present at the same port of a circulator from which the isolation leakage signal flows to the error correction component.
