Application of signal processing worksystem simulation in Look-up table prodistorter design

In this paper, we introduced various HPA models based on Volterra series and its simplified form and described an adaptive Look-up table (LUT) algorithm. The predistortion design and simulation were setup in signal processing worksystem (SPW) software. The simulation result shows that the proposed method can reduce the system bit error rate (BER) and improve system performance effectively.
