Annotation: Various option for design of intermodulatuion distortion compensation system are discussed. The review considers the publications appeared in international scientific journals. The article highlights a typical structure of nonlinear dynamic block mathematic model, variation of pridistorter architecture and algorithms of predistorter adaptation. Comparative of predistortion system is presented.
