    摘要: According to at least one aspect, a communication system is provided. The communication system includes a power amplifier configured to amplify an input signal to generate an amplified output signal and provide the amplified output signal to an antenna, a power supply coupled to the power amplifier and configured to provide power to the power amplifier based on a power supply control signal, and a controller coupled to the power supply. The controller is configured to identify a target transmit power level for transmission of a wireless signal, generate the power supply control signal based on the target transmit power level using information indicative of a relationship between the target transmit power level and a setting of the power supply, generate performance information indicative of a characteristic of the communication system when the wireless signal is transmitted, and update the information indicative of the relationship using the performance information.
