Patent ID: 7787566

Claim:
A power management system for powering an output power amplifier block in a wireless communication device, the power management system comprising: an average power and gain control block configured to provide a gain control signal and an average desired transmit power signal, the average desired transmit power signal being based on at least one of a power control instruction signal and a received signal strength indicator signal; an environmental sensor configured to provide at least one environmental information signal; and, a power supply level adjustment generator implemented by a plurality of look-up tables, and configured to provide a power supply level adjustment signal based on a data parameter indication of a baseband outgoing data stream to be transmitted by the wireless communication device and the at least one environmental information signal, wherein one look-up table is provided for each of the at least one environmental information signal and the data parameter indication, and outputs of each look-up table are combined to generate the power supply level adjustment signal; and, a power supply module connected to the average power and gain control block and the power supply level adjustment generator, and configured to provide a variable power supply signal to the output power amplifier block based on the average desired transmit power signal and the power supply level adjustment signal.
