Paper Abstract

To achieve adaptive modulation technology in Optical Orthogonal Frequency Division Multiplexing (OOFDM) system, the channel estimation has to be made first and foremost. By imposing a symbol of pilot signals after a certain amount symbols, the frequency response of a given transmission link can be given out. The modulation format can be determined according to the frequency response. A high (low) modulation format is used on a sub-carrier suffering a low (high) transmission loss. The modulation format can be adjusted adaptively.
