US 2014/0349593 A1 · METHOD AND APPARATUS FOR CALIBRATING AN ITERATIVE MATCHING NETWORK TUNER

Abstract

A system that incorporates teachings of the subject disclosure may include, for example, identifying a usage mode of the communication device, running a calibration session that includes adjusting a starting point for tuning of the matching network based on a categorized history of previous tuning search paths and based on the usage mode where the categorized history of previous tuning search paths is generated based on monitoring previous tuning search paths during previous tuning and based on monitoring previous usage modes during the previous tuning, and adjusting a tuning search path for the tuning of the matching network based on the categorized history of previous tuning search paths and the usage mode where the adjusting of the starting point and the adjusting of the tuning search path reduces a tuning search time and provides a unique solution for the tuning. Other embodiments are disclosed.
