The apparatus includes a preprocessor configured to preprocess a transmitted signal according to a pre-obtained preprocessing coefficient and a predistorter configured to perform predistortion for the preprocessed signal, and a result of comparison of a characteristic parameter of the signal that has been preprocessed and then predistorted with that of the transmitted signal satisfies a predetermined condition. By preprocessing the transmitted signal at the transmitter end, the embodiments of the present disclosure may perform efficient nonlinear compensation only needing to measure at the transmitter end and without needing to perform many times of measurement at the receiver end, and may lower complexity of circuits of the communication system and complexity of calculation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonlinear compensating apparatus and method, transmitter and communication system","description":"A nonlinear compensating apparatus and method, a transmitter and a communication system are provided.
