Abstract: In the present power control technique, a power control circuit (404) that is operably coupled to a receiver circuit (412) assesses (514, 522) a tclip adjust value based on a power cutback value from the receiver circuit. The tclip adjust value is forwarded to a peak to average ratio control circuit (402) operably coupled to the power control circuit (404), and using the tclip adjust value, an adjust peak power signal is accordingly assessed (612).

Abstract: A radio frequency module (500) that uses reconfigurable and reprogrammable hardware to generate and condition RF signals that have one of several selectable modulation formats. A modulation controller (316) selects a selected modulation format from a plurality of modulation formats and a signal generator (408) that is capable of generating a signal modulated with any modulation format within the plurality of modulation formats generates a signal (520) modulated with the selected modulation. A signal filter (406) filters the signal according to one algorithm of a plurality of algorithms that is selected based upon the selected modulation format to produce a filtered signal (522). A signal linearizer (404) adaptively compensates the filtered signal (522) for distortions introduced by processing of the signal.

Abstract: A method (200) of frequency drift prediction for use by a positioning receiver (106) can include the steps of determining (202) a moving average of a frequency error, determining (206) a moving average of a frequency drift rate in a communication device, determining (212) a frequency drift rate uncertainty, and providing (214) the moving average of frequency error and frequency drift rate, and the frequency drift rate uncertainty to the positioning receiver. A point-to-point slope from the running average of the instantaneous frequency error and a running average of the point-to-point slope for a predetermined time period can be determined (208 & 210). The frequency drift uncertainty or window is determined using information determined from the moving average of the frequency drift rate. The positioning receiver can be a global positioning receiver.

Abstract: A wireless communications device, such as a cellular telephone (200), is able to accept and process DTMF tones as commands. Appropriate DTMF tones control operating characteristics of the wireless communications device (200). An example is causing a cellular phone to ring even though it has been configured into a “vibrate only” silent ring mode or a mode which has disabled all incoming call notification. Operation of such a DTMF tone facilitates finding a lost or misplaced cellular phone when that phone is configured to not ring in response to other calls. An external data communications port (232) of the wireless communications device (200) can also be controlled or data specified by the DTMF tone can be transmitted out of that data communications port (232).
