Disclosed in an embodiment of the present application are a pre-distortion parameter obtaining method and pre-distortion system for simplifying calculating complexity of a model while achieving good signal processing effect. The method comprises: after the beginning of periodic filtering processing, obtaining a pre-distorted signal after pre-distortion processing and a first feedback signal after power amplification (S101); obtaining a second feedback signal by eliminating the rated linear gain of the first feedback signal (S102); determining a pre-distortion parameter according to a matrix formed by the second feedback signal and a matrix formed by the pre-distorted signal (S103); updating the pre-distortion parameter index table according to the determined pre-distortion parameter (104)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital pre-distortion parameter obtaining method and pre-distortion system","description":"The present application relates to the field of digital pre-distortion processing.
