Abstract:
1. A power management system for a transmitter of a wireless device, the transmitter comprising a power amplification block for generating an amplified transmission signal, and the power management system comprising: an environmental sensor unit for providing at least one environmental information signal representing an operating environment of the mobile device; and a power supply level adjustment generator configured to receive the at least one environmental information signal and to generate a power supply level adjustment signal by combining power supply level adjustment values stored in a plurality of look-up tables comprising one look-up table for each of the at least one environmental information signal and a data parameter indicator of a baseband outgoing data stream to be transmitted by the wireless device, the power supply level adjustment signal for combining with an average desired transmit power signal representing an average transmit power of the amplified transmission signal to generate a variable power supply signal for the power amplification block.
