Abstract

A matching system of a communication device that incorporates teachings of the present disclosure may include, for example, a controller that executes instructions facilitating selection of a subset of usage scenarios according to a usage condition of a communication device. An impedance circuit is adjusted based on a subset of different tuning scenarios corresponding to the subset of usage scenarios to facilitate an impedance match to an antenna of the communication device. A group of operational parameters is obtained for each tuning scenario change between the subset of different tuning scenarios. Multiple operational parameters obtained at each of the subset of different tuning scenarios at different times are processed for each tuning scenario and a tuning scenario is selected based on a determination as to which of the processed operational parameters correlates with a predetermined performance goal. Additional embodiments are disclosed.
