APARATUS AND A METHOD FOR PROCESSING AND AMPLIFYING A SIGNAL

A method and an apparatus. The apparatus includes at least one sensor for sensing at least one parameter that affects a non-linearity of the non-linear amplifier and for generating at least one parameter indicator; a memory module for storing multiple sets of pre-distortion coefficient values; a ret...

Zusammenfassung:	A method and an apparatus. The apparatus includes at least one sensor for sensing at least one parameter that affects a non-linearity of the non-linear amplifier and for generating at least one parameter indicator; a memory module for storing multiple sets of pre-distortion coefficient values; a retrieval module, coupled to the memory module, for receiving the at least one indicator, for selecting a selected set of pre-distortion coefficient values based on the at least one indicator, and for sending the selected set of pre-distortion coefficient values to a signal processing module; and a signal processing module, configured to receive an input signal, to receive the selected set of pre-distortion coefficient values, and to pre-distort the input signal, using the selected set of pre-distortion coefficient values such as to at least partly compensate for the non-linearity of the non-linear amplifier.
