摘要：
A new channel estimation method is proposed based on fast orthogonal frequency-division multiplexing (FOFDM), which can be effectively used in our experiment based on intensity modulation and direct detection. In this experiment, the FOFDM subcarrier channel spacing is half of the symbol rate. The spectral efficiency of FOFDM is twice as large as that of OFDM, which can also be verified in our experiment.
