A novel method for distortion suppression in radio over fiber communication systems using FBG

Abstract

In this paper, a linearization method that reduces nonlinear distortion and increases receiver sensitivity of radio over fiber (RoF) links is discussed. The design also addresses the RoF system without significantly adding great expense and complexity to the system. The proposed method is capable of suppressing both second- and third-order distortions despite the RF carrier that is used. Additionally, it is shown to surpass the traditional RoF systems in terms of BER and receiver sensitivity.
