A High Efficiency PA Modeling Approach for DPD Based on Memory Polynominal
Digital predistortion is a predominant technique for the linearization of power amplifier. Memory polynomial is often used to describe the PA model with memory effect. In this paper, based on memory polynomial, a new PA modeling approach which combines look-up table with characteristic time-delay is proposed. Simulation results show that the DPD based on this proposed PA modeling can decrease computational complexity and increase operation frequency significantly.
