Polynomial Predistortion linearizing device, method, phone and base station

摘要

A device (400), method (1200), phone (400) and base station (400) provide predistortion for linearization in a radio frequency RF power amplifier. The method includes the steps of: A) predistorting (1201) a baseband signal to provide a predistorted baseband signal in accordance with real-time polynomial coefficients; B) modulating (1202) the predistorted baseband signal to provide an RF signal; C) amplifying (1203) the RF signal to provide an amplified RF signal; D) demodulating (1204) the amplified RF signal to provide a demodulated baseband signal; and E) estimating (1205) the real-time polynomial coefficients to provide a linear amplified RF signal.
