Abstract
A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium having computer instructions to perform actual measurements of one or more performance parameters of a communication device according to a subset of tuning states of a tunable matching network operable in a communication device, determine estimated measurements of the one or more performance parameters of the communication device for a portion of the tuning states not included in the subset of tuning states according to the actual measurements, identify a data set for each of the one or more performance parameters from at least portions of the tuning states and the actual and estimated measurements, and determine from at least a portion of the date sets one or more tuning states that achieve at least one desirable performance characteristic of the communication device. Additional embodiments are disclosed.
