Abstract
Attenuation is provided at the output of a power amplifier that provides transmitted signals or packets. The attenuation particularly provides separation of linear and non linear behavior of the signals. A reference packet is transmitted during attenuation. A normal packet is delivered without attenuation. Feedback from the reference packet can be extracted using the normal packet to calculate a loop-back response that is extracted and sent to a power amplifier pre-distortion correction algorithm.
