This paper presents a new radio frequency power amplifier behavioral model that is capable of modeling long term memory effects. The proposed model is derived by assuming linear dependence of the parameters of a conventional model to a long term memory parameter, which enables the model to better track the signal-induced changes of the power amplifier electrical behavior. The model is experimentally...
In this paper efficient computer implementations of some of the most commonly used Volterra series based power amplifier behavioral models are proposed. The desired efficiency is in regard to algorithm complexity and floating point operations. Finally a comparative overview of the different behavioral models with respect to their complexity is presented.
We propose a framework for complexity analysis of Volterra series and derivatives thereof, and formulate a constrained Volterra-based series aimed at reducing computational complexity.
