DIGITAL PREDISTORTION SYSTEM AND METHOD FOR CORRECTING MEMORY EFFECTS WITHIN AN RF POWER AMPLIFIER

摘要

A system and method of correcting memory effects present within power amplifiers using digital predistortion and an improved power amplifier system employing digital predistortion are disclosed. Nonlinearities within a power amplifier (110) having an input derived from a digital signal are compensated by injecting a digital correction signal prior to the power amplifier (110). A system and method for modeling the distortion created by power amplifier (110) memory effects and generating the desired digital predistortion correction signal are disclosed.
