摘要： A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.

摘要： A communications device, in one aspect as a portable wireless communications device, includes an in-phase modulator and power amplifier that receives a baseband I signal and modulates and amplifies the I signal. A quadrature modulator and power amplifier receives a baseband Q signal and modulates and amplifies the Q signal. A power combiner sums and outputs the I and Q signals. An I demodulator circuit receives a signal fed back from the I power amplifier and demodulates the fed back signal to produce demodulated I signals. A Q demodulator circuit receives a signal fed back from the Q power amplifier and demodulates the fed back signal to produce demodulated Q signals. A processor compares the digital, baseband I and Q signals with a demodulated I and Q signals to compensate for amplitude, frequency and phase modulation errors.

摘要： A system and method for speed measurement of a mobile device (300), using a speed sensor (460) such as a satellite navigation system (460) or an accelerometer, does not need such speed sensor (460) to be continually activated. The system and method make use of a monitor (471) for monitoring at least one motion indicium for indicating that the speed of the mobile device (300) is above an initial threshold (112), including but not limited to: monitoring the Doppler shift measurements of a timing signal; monitoring the timing advance of a cellular radio signal; monitoring the number of base stations (511) visible to the mobile device (300); monitoring the frequency of base station handover, however determined; monitoring the level crossings and/or the autocorrelation of an RSSI signal; and/or triangulation of the position of the mobile device (300). When the monitor (471) determines that the mobile device (300) may be travelling in excess of a threshold speed (112), a speed sensor (460) is activated to confirm the indication. If the speed sensor (460) determines that the mobile device (300) is travelling at a speed below a second threshold (171), the speed sensor (460) is deactivated.
