Abstract
In this paper, a new deviation-reduction approach is proposed to simplify the structure of Volterra series based behavioral models, aimed at significantly reducing the complexity of this kind of model for RF/microwave power amplifiers. The proposed model reduction method is based on a new format representation of the Volterra series, which is extended from a previously-introduced "modified Volterra series" but adapted to a complex baseband formulation in the discrete time-domain. This model can be easily extracted directly from measured time-domain samples of input and output signals of an amplifier by employing simple linear system identification algorithmsKeywords
