ABSTRACT:
Calibrating a transmit diversity device includes establishing diversity parameter values of diversity parameters for a plurality of signals, where each signal is transmitted from a channel of the transmit diversity device. The following are performed for each diversity parameter value to yield associations: determining a modification parameter value that yields a diversity parameter value, where a modification parameter value describes modulation of a feature of at least one signal; and associating the modification parameter value with the diversity parameter value to yield an association. Calibration data is generated in accordance with the associations.
