The circuit comprises a primary pre-distorter module configured to generate a pre-distorted signal y(n) based on the input signal x(n) and a primary pre-distortion function parameterized by a pre-distortion parameter λ and to feed the pre-distorted signal y(n) to the non-linear component. The circuit comprises an estimation module. The estimation module is configured to receive samples z(n) of the output signal Sout, and to determine the pre-distortion parameter λ. The estimation module comprises a secondary pre-distorter module configured to generate a secondary pre-distorter output signal r(n) based on a secondary pre-distortion function and the samples z(n) of the output signal Sout. The secondary pre-distorter module is configured to determine the pre-distortion parameter λ based on a previously determined pre-distortion parameter stored on a data storage, the secondary pre-distorter output signal r(n) and the pre-distorted signal y(n) provided by the primary pre-distorted module. The determining comprises correlating the input signal x(n) with an error signal between the pre-distorted signal y(n) and the secondary pre-distorter output signal r(n)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuits for linearizing an output signal of a non-linear component and related devices and methods","description":"This disclosure provides a circuit for linearizing an output signal Sout produced by a non-linear component based on an input signal x(n).
