Patent ID: 7885618

Claim:
A method for collecting calibration data, comprising: sending a plurality of commands to a transmit diversity device, said commands to cause said transmit diversity device to transmit a respective plurality of signals; receiving at a calibration system said plurality of signals from said transmit diversity device, each signal of the plurality of signals transmitted from a channel of a plurality of channels of a transmit diversity device, the plurality of signals generated according to a plurality of command points, a command point comprising a plurality of command parameter values of a plurality of command parameters; establishing a null value for each command parameter of the plurality of command parameters to yield a plurality of null values, a null value for a command parameter representing a command parameter value that yields a minimum signal feature value of a signal feature; and determining a signal feature value for each command point of the plurality of command points in accordance with the plurality of null values to yield a plurality of signal feature values; associating at least one signal feature value of the plurality of signal feature values with a command point that substantially yields the at least one signal feature value; and storing a table of said associations of signal feature values with command points in a memory in said calibration system.
