Abstract: A non-linearity correction circuit includes a non-linearity coefficient estimation circuit. The non-linearity coefficient estimation circuit includes a data capture circuit, a non-linearity term generation circuit, a time-to-frequency conversion circuit, a bin identification circuit, a residual non-linearity conversion circuit, and a non-linearity coefficient generation circuit. The non-linearity term generation circuit is coupled to the data capture circuit. The time-to-frequency conversion circuit is coupled to the data capture circuit and the non-linearity term generation circuit. The bin identification circuit is coupled to the time-to-frequency conversion circuit. The residual non-linearity conversion circuit is coupled to the bin identification circuit. The non-linearity coefficient generation circuit is coupled to the bin identification circuit and the residual non-linearity conversion circuit.

Abstract: Examples of this description provide for a method. In some examples, the method includes determining, via a circuit, an estimated value of harmonic coupling in a transmitted signal via a feedback signal path that receives the transmitted signal and performing pre-compensation for the harmonic coupling based on the estimated value, the pre-compensation performed in the circuit.

Abstract: A technique for reinitializing a coupled circuit, the technique including receiving a common configuration value associated with states of a coupled circuit, tracking states associated with the coupled circuit while the coupled circuit is in a low power state based on the common configuration value, receiving the tracked state associated with the coupled circuit, receiving a scaling value associated with the coupled circuit, determining a current state of the coupled circuit based on the tracked state and the scaling value, and transmitting an indication of the current state to the coupled circuit when the coupled circuit has exited the low power state.
