  • Abstract
    This paper introduces an algorithm for estimating loop-delay in digital predistortion (DPD) system. The algorithm includes two parts: integer loop-delay estimation and fractional loop-delay estimation. The integer loop-delay estimation adopts correlation function and digital differentiator to search the estimate. The fractional part gets the convergence value through LMS algorithm based on interpolation filter structure. Finally, the validity of the algorithm and the effect for DPD system is proved through the experiment simulations.
