A predistortion algorithm based on a memory-based power amplifier model (PA) is presented. The algorithm was tested using a PA measurement system. The predistortion techniques are based on the filtered tapped delay line (TDL) model. Memoryless predistortion techniques are also presented to show the benefits of the memory-based predistortion approach. Memoryless predistortion reduces third order IM by 5-8 dB, while memory-based predistortion reduces third order IM by 18-20 dB.
