Abstract

We show numerical simulation results of three different timing synchronization methods in OOFDM system using Intensity-Modulation and Direct-Detection (IMDD) in Multi-Mode Fiber (MMF) channel and do comparative study of the three algorithms. Based on Park’s algorithm, we present a modification to it that gets a very sharp timing metric curve.
