Patent ID: 8472888

Claim:
A method, comprising: selecting a subset of tuning states of a tunable matching network coupled to an antenna of a communication device, wherein the tunable matching network has a tunable reactance that affects a plurality of performance parameters of the communication device, wherein the plurality of performance parameters are associated with a receive mode and a transmit mode of the communication device; performing actual measurements of the plurality of performance parameters of the communication device according to the subset of tuning states; determining estimated measurements of the plurality of performance parameters for a portion of the tuning states not included in the subset of tuning states according to regression analysis of the actual measurements of the plurality of performance parameters; identifying a data set for each of the plurality of performance parameters from the tuning states and the actual and estimated measurements; and determining from at least a portion of the plurality of data sets one or more tuning states of the tunable matching network that achieves a performance characteristic of the communication device.
