Implementation Aspects of the Baseband Digital Predistortion Linearizers
Original language description
Digital predistortion is one of the most popular techniques to combat the power amplifier (PA) nonlinearities in modern transceivers. In order to adjust the predistorter parameters to the time, temperature and frequency variations of the amplifier, the predistorter is required to be adaptive. Two main families of the predistorter adaptation can be distinguished ? direct and indirect learning. Current transceiver architectures tend to multiband, multimode and multistandard implementations, where the amplifier (and so the predistorter) must work in wide frequency range and with various types and bandwidths of digital modulated signals. The predistorter as well as the amplifier is usually modeled by one of the following functions ? the Look-Up-Table (LUT), polynomial function, memory polynomial, orthogonal polynomial etc.
