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.

Establishing slot boundaries includes receiving a feedback signal reflecting feedback information describing a signal modified according to a diversity parameter adjustment. The feedback signal includes slots and bits. A slot boundary is established for each of the slots by: partitioning the bits into periods; comparing the bits of each period; and establishing the slot boundaries in accordance with the comparison.

A method for enhancing data wipeoff by predicting future navigation data. Data wipeoff using predicted future navigation data reduces or eliminates incomplete data wipeoff, thereby enhancing GPS receiver sensitivity and reducing acquisition times. Predicting future navigation data involves receiving navigation data and using the received navigation data to generate predicted future navigation data, wherein the predicted future navigation data should be approximately identical to navigation data received at a future time. The predicted future navigation data is subsequently used to perform data wipeoff.
