Minimization of Feedback Loop Distortions in Digital Predistortion of a Radio-Over-Fiber System With Optimization Algorithms
This article proposes the linearization of an intensity modulation/direct detection radio-over-fiber (RoF) link with feedback loop.The goal is to carry out the predistortion process in a real scenario, in which the output signals are a few kilometers far from the baseband unit (BBU).First, the MOISTURIZING MASK feedback loop is considered ideal, so
