Paper Abstract
We propose adaptively loaded set-partitioned offset quadrature amplitude modulation (SP-offset-QAM) orthogonal frequency division multiplexing (OFDM) for low-cost intensity-modulation direct-detection (IM/DD) communication systems. We compare this scheme with conventional OFDM in 40-Gbit/s experiments over 50-km single-mode fiber. It is shown that the use of SP-QAM formats, together with the adaptive loading algorithm specifically designed to this group of formats, improves the performance of offset-QAM OFDM. It is also shown that the proposed scheme exhibits better performance than SP-QAM based conventional OFDM at back-to-back and after 50-km transmission.
