Claim 0:
1. A method comprising:
receiving, by a power supply modulator, one or more control signals; and
regulating, based on the one or more control signals, power supply provided to a power amplifier of a transmit chain to underpower the power amplifier so that the transmit chain includes at least some non-linear behavior;
wherein the at least some non-linear behavior of the transmit chain, resulting from regulating the power supply based on the one or more control signals, is at least partly mitigated through digital predistortion performed by a digital predistorter on signals comprising an input signal, u, provided to the digital predistorter, and on another signal, provided to the digital predistorter, that depends on amplitude variations based on the input signal, u, wherein the variations of the other signal correspond to time variations in non-linear characteristics of the transmit chain.
