Currently,timing synchronization methods in the CO-OFDM system are proposed for wireless communication.Optical fiber channel has several significant differences with Wireless channel.One of the most important differences is chromatic dispersion of fiber.This key factor degrades many timing synchronization methods.In this paper,by analyzing the drawbacks of the typical Schmidl&Cox algorithm,we propose a proposed method and simulate the two algorithms using MATLAB programs in optical fiber channel models.The ...
