MINIMIZATION OF FEEDBACK LOOP DISTORTIONS IN DIGITAL PREDISTORTION OF A RADIO-OVER-FIBER SYSTEM WITH OPTIMIZATION ALGORITHMS

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 Birthstone Memorial Necklace real scenario, in which the output signals are a few kilometers far from the baseband unit (BBU).First, the feedback loop is considere

An adaptive instinctive reaction strategy based on Harris hawks optimization algorithm for numerical optimization problems

An adaptive Harris hawks optimization (HHO) algorithm is proposed to solve the non-linearly constrained optimization problems.The algorithm, namely, instinctive reaction strategy based on HHO (IRSHHO), combines the instinctive reaction strategy (IRS) with the HHO algorithm.In IRSHHO, the increment of step length decreases with the increase in the i
