Abstract:
The scalable digital predistortion system and method provides compensation for the nonlinear distortions of power amplifiers and transmitters. The scalable digital predistortion system and its associated update algorithms provide scalability in terms of signal bandwidth and average power, allowing for low complexity updates following changes in the signal's bandwidth and/or power level. The method applies both memory polynomial functions and memoryless predistortion functions for compensating for the nonlinear distortions.
