Abstract

Power amplifier time-delay invariant predistortion methods and apparatus are based on the stored-compensation or memory-compensation principle by using a combined time-delay addressing method, and therefore, the architecture of the apparatus has an intrinsic, self-calibrating time-delay compensation function. The architecture only uses a lookup table (33) to conduct both the correction of non-linear responses of a power amplifier (12) and the compensation of any time-delay effects presented in the same apparatus. Due to the time-delay invariant characteristic, the predistortion design has a wider dynamic range processing advantage for wireless RF signals, and therefore can be implemented in multi-carrier and multi-channel wireless systems.
