Method and apparatus for calibrating a communication device

A method, comprising:

• obtaining, by a system including a processor, a measurement of a performance parameter of a communication device according to a subset of tuning states of a tunable reactive element of the communication device, wherein the performance parameter is associated with a receive mode and a transmit mode of the communication device;
• estimating, by the system, a measurement for the performance parameter for at least a portion of the subset of tuning states not included in the subset of tuning states according to regression analysis applied to at least portions of the obtained measurement;
• determining, by the system, a multi-dimensional data set for the performance parameter from at least portions of the tuning states, the obtained measurement and the estimated measurement;
• and
• enabling a user selection of at least a subset of the tuning states for storage in a look-up table which can be used by the communication device for tuning the tunable reactive element while the communication device is in operation.

A communication device, comprising:

• an antenna;
• a transceiver;
• a tunable matching network coupled with the antenna and the transceiver, wherein the tunable matching network comprises at least one of a first tunable reactance circuit having at least one tunable reactive element, or a second tunable reactance circuit having at least one switchable element that enables or disables at least one fixed reactance element;
• a memory to store instructions;
• and
• a processor coupled to the memory, wherein execution of the instructions by the processor causes the processor to perform operations comprising:
• retrieving actual measurements of a performance parameter of the communication device according to a subset of tuning states of the tunable matching network;
• determining estimated measurements of the performance parameter for at least a portion of the tuning states not included in the subset of tuning states based on the actual measurements;
• identifying data sets for the performance parameter from at least portions of the tuning states and the actual and estimated measurements;
• and
• determining from at least a portion of the data sets tuning states that achieve a performance characteristic of the communication device.
