Abstract: Coherent optical OFDM (CO-OFDM) is a promising technology for the next-generation optical transmission systems beyond 100 GB/s which has been proposed recently and its implementation has shown extreme robustness against chromatic dispersion and polarization mode dispersion. The proposed synchronization method provides better results when compared with Schmidl, Minn and Parkβs methods in terms of timing and frequency offset estimation. Since CO-OFDM is sensitive to noises, channel estimation plays an important role in detecting baseband data from the received signal. A DFT based channel estimation technique is proposed which gives a better performance when compared to conventional LS and MMSE methods.
