Beschreibung
Zusammenfassung:	A radio system, comprising an antenna; a baseband module, a power amplifier; and a variable power supply. The baseband module is configured to output a first signal to the antenna, pre-distort the first signal based on computed coefficients, and output a second signal. The second signal is determined based on one or more characteristics of the first signal, and the second signal is output if there is a change in the one or more characteristics of the first signal. The power amplifier is communicatively coupled to the baseband module and the antenna, and is configured to amplify the pre-distorted signal. The variable power supply is communicatively coupled to the power amplifier and the baseband module. The variable power supply is configured to receive the second signal and generate a variable drain supply voltage corresponding to the second signal. The drain supply voltage is output to the power amplifier.
