Abstract :
Much research effort has recently been devoted to the design and implementation of high linearity feed-forward power amplifier for wireless communication systems. This paper presents two novel DSP (digital signal processing) algorithms that can substantially improve the tracking performances of the adaptive control loops. Both computer simulation and experimental results are included for verification.
