Abstract
We experimentally demonstrate an intensity modulated and direct detection optical OFDM with variable bit rate from 5Gb/s to 8Gb/s using BPSK format and reducing the guard band up to 75% over 25km SSMF. A fast processing based on Hartley transform is performed achieving the same performance as 4QAM FFT-based processing with low complexity DSP.
