Adaptive digital predistortion to linearize nonlinear distortion in radio-over-fiber links [PDF]
, 2021 The application of Radio-Over-Fiber (ROF) links are widely used in wireless communications. However, due to the nonlinear characteristics of the link distortion will be introduced as the output of the link. As a result, unwanted frequencies and signals end up being delivered by an antenna. In the thesis, a technique of adaptive digital predistortion is
