WebOptical OFDM to Combat Chromatic Dispersion in Long-Haul Systems. Description. Orthogonal Frequency Division Multiplexing (OFDM) is a widespread technology in broadband communication (wired and wireless) because of its ability to cope with strong channel distortions (interference, frequency fading, multipath propagation). WebSynchronization at the receiver of a practical orthogonal frequency division multiplexing (OFDM) system design is one of the most crucial data detection stages that must be performed accurately in order to avoid system performance degradation due to symbol timing and carrier frequency offset [ 1 ].
