Document Type and Number:
WIPO Patent Application WO/2017/113785
Kind Code:
A1
Abstract:
A predistortion model adjusting method and device. The method comprises: verifying a look-up table (LUT) of a predistortion system to determine whether the LUT satisfies a predetermined condition; if the LUT does not satisfy the predetermined condition, determining that model parameters (MPs) need to be updated; when determined that the MPs need to be updated, selecting model parameters from a model parameter set such that the distortion performance of the predistortion system is optimal, thereby obtaining a predetermined predistortion model according to the selected model parameters. The embodiments of the present invention realize update of MPs in a predistortion model when an LUT is not applicable for current MPs, thus reducing the time for re-determining the predistortion model and improving the applicability and performance of the predistortion system.
