Channel estimation based on adaptively modulated optical OFDM

摘要：

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.
