Abstract
We propose a symmetric spectrally-efficient frequency-division multiplexing (SEFDM) scheme using a logarithmic-maximum-a-posteriori (log-MAP) based detecting algorithm with reduced complexity due to I/Q separation, and successfully demonstrate 200-Gb/s optical SEFDM transmission using 16-QAM modulation over 500-m of standard single mode fiber (SSMF), with a bandwidth compression factor (BCF) of 0.8.
