SYSTEMS AND METHODS FOR INCREASING THE EFFECTIVENESS OF DIGITAL PRE-DISTORTION IN ELECTRONIC COMMUNICATIONS

摘要

Various embodiments of communication systems and methods in which the communication system is operative to find, record, and use sets of pre-distortion parameters in conjunction with a pre-distortion procedure, in which each set of pre-distortion parameters is operative to specifically counter distortions produced in a power amplifier by a specific combination of level of input signal power and level of analog gain associated with a transmission path of the communication system. In some embodiments, there is a modulator, a transmission chain, a distortion analysis mechanism, and a pre-distortion mechanism, operative to analyze and modify signals so as to counter signal distortion.

1. A method for managing pre-distortion procedures, comprising:
determining, by a communication system, a first set of transmission parameters associated with a transmission chain belonging to said communication system, the first set of transmission parameters comprising (i) a first level of power associated with a first transmission signal feeding said transmission chain, and (ii) a first level of analog gain as applied by said transmission chain to said first transmission signal; finding, by said communication system, a first set of pre-distortion parameters associated with a pre-distortion procedure operative to counter distortions produced in conjunction with said first set of transmission parameters in a power amplifier belonging to said transmission chain; and applying, by said communication system, said pre-distortion procedure, using said first set of pre-distortion parameters, thereby at least partially countering said distortions.
