Abstract
An output signal from an inherently non-linear device is linearized by sampling an original signal with a first sampling rate for a desired signal resolution of an achieved digital original signal message; and re-sampling the original signal at a second sampling rate for creating a digital pre-distortion signal to be added to the achieved digital original signal message. The second sampling rate is greater than the first sampling rate, thereby forming a digital pre-distorted signal to be fed to the inherently non-linear device after digital to analog conversion.
