Abstract
Recursive digital pre-distortion (DPD) techniques are provided. Digital pre-distortion is performed by applying a signal to a recursive system to generate a state vector; providing the state vector as a feedback value to the recursive non-linear system; and applying the state vector to a second function to generate an output signal, wherein at least one of the recursive system and the second function comprise a non-linear function. The recursive non-linear system can be initialized to a known initial value. The recursive system is defined by a system of non-linear differential equations.
