Abstract
Apparatus, method therefor, generally related to signal preconditioning. In such an apparatus, a signal classifier block and a delay block are commonly coupled for receiving an input signal. The delay block is for providing a delayed version of the input signal. The signal classifier block is for classifying the input signal and generating a configuration signal having configuration information for digital predistortion (“DPD”) engine parameterization in response to the input signal classification. A DPD engine is for receiving the delayed version of the input signal and the configuration signal and for providing a predistorted output signal.
