Claim:
1. A communication system to manage pre-distortion procedures, comprising: a transmission chain comprising a power amplifier, said transmission chain is associated with a level of analog gain that is configurable by said communication system; a modulator to feed said transmission chain with a transmission signal having a level of power that is configurable by said communication system; wherein said communication system is configured to find, record, and use sets of pre-distortion parameters in conjunction with a pre-distortion procedure, each said set of pre-distortion parameters to specifically counter distortions produced in said power amplifier by a specific combination of said level of power and said level of analog gain; further comprising a distortion-analysis mechanism to derive said sets of pre-distortion parameters by analyzing distortions in an output signal produced by said power amplifier in conjunction with said specific combinations of said level of power and said level of analog gain;
