| Abstract: | Based on FPGA chip Stratix Ⅱ EP2S60F672C,this paper designed and implemented a loop-delay estimation model in predistortion system.This model used a novel method of estimate the loop-delay,which is easy to implement in FPGA,and can give the right loop-delay estimation value under the condition of signal distortion.The timing simulation result of Modelsim SE 6.5c and hardware debugging result of SignalTap Ⅱ verified the valid of the model designed in this paper. |
