On the basis of the analysis of the fundamental principles of digital pre-distortion（DPD）,the design scheme of IP core based WCDMA（Wideband Code Division Multiple Access） digital intermediate frequency pre-distortion system is provided.The FPGA made by XILINX with DPD specific IP core was applied in this scheme.Furthermore,the general block diagram of DPD system was structured with this scheme,and the software and hardware tests of DPD were also conducted.The simulation results showed that the application of DPD could significantly improve the system performance.
