Open the CIPO recordAbstract From the Canadian patent
A complex baseband model of the power amplifier within a DSP domain is used to develop a feedback signal that would be equivalent to the optimum negative feedback, used for the analog amplifier. Once the feedback signal is available it can , be processed, to compensate for the effects of the group delay and for optimum loop gain hence, resulting in a broadband response with no theoretical limitations on the linearization of, the amplifier.
