1. A system, comprising: a radio frequency receiver configured to receive an undistorted signal; a separation block configured to: generate, using a plurality of adaptable coefficient multipliers, a reference signal component of a signal and an error signal, wherein the signal is a distorted version of the undistorted signal, update the plurality of adaptable coefficient multipliers based on the error signal, and generate, based on the reference signal component, a target signal component of the signal; a digital signal processor (DSP) configured to: filter the reference signal component according to a plurality of filter coefficients to provide an output signal that is substantially similar to the target signal component, and adjust the plurality of filter coefficients to drive a feedback signal to a predetermined level; and a combiner configured to subtract the output signal and the target signal component to provide the feedback signal.
