Two modified timing synchronization methods are proposed for coherent optical OFDM system to solve the ambiguity problem in Park’s and Minn’s methods. It is confirmed that the proposed modified Park’s method can obtain higher time estimation accuracy, and the modified Minn’s method is more robust both to CD and PMD.
