Abstract
Examples described herein provide a radio frequency circuit. The radio frequency circuit includes a controller; a parameter estimator circuit; a capture circuit; and a pre-distorter circuit. The pre-distorter generally includes one or more nonlinear filter circuits and configurable hardware circuitry. Each of the one or more the nonlinear filter circuits includes: adder(s); multiplier(s); and memories coupled to at least one of the adder(s) and the multiplier(s); where the configurable hardware circuitry is configured to distort one or more input signals by directing the one or more input signals along a path through the one or more adders, the one or more multipliers, and the one or more memories and by distorting the one or input signals using the nonlinear parameters stored in the one or more memories as the one or more input signals travels the path.
