A Linearization Method of Non-linear Communication Paths based on A Complex Model
Osamu Ichiyoshi (HNB21C) SANE2019-46
Abstract (in Japanese) (See Japanese page) 
(in English) Nonlinear distortions of amplifiers can bring serious degradations in communication. A practical linearization method to reduce the nonlinear distortion is pre-distorter [1,2]. The conventional pre-distorters require the knowledge in advance about the nonlinear performances of the amplifiers in communication links, which is not available in many applications. As they are of open loop circuits, they cannot follow the changes of the nonlinear properties of the amplifiers in time either.
In order to solve those problems the author proposed a negative feedback linearizer for non-linear amplifiers based on a complex model a few years ago [3]. The negative feedback linearizer can not only cope with wide varieties of nonlinear properties of the amplifiers without the advance knowledge of the communications paths but also can follow the changes of parameters in time. The method is also applicable to cases with large paths delays.
The proposed method is based on a complex model of nonlinear amplifiers. The model is analyzed based on a stray capacity theory modeled as the balance between electrical and mechanical forces in the stray capacitors.
