OWDM system based on ML algorithm and blind identification in multipath fading channel

A novel OWDM system with blind identification based on the maximum likelihood (ML) algorithm is studied for the multipath fading channel. New OWDM structures based on the ML algorithm and blind identification and H~ matrix based on the ZF (zero forcing) algorithm are the two novel aspects of this system. The performance of the system under the multipath fading channel is analysed.
