From 4.2Gbps Asymmetrical Clipping (ACO)-OFDM to 8.7Gbps Layered-ACO-FBMC with Intensity-Modulation Direct-Detection for PONs

Orthogonal frequency division multiplexing (OFDM) has been extensively explored as a potential candidate for future next generation of passive optical networks (PONs) ought to its numerous benefits such as high robustness to chromatic dispersion since cycle prefix (CP) is used, and efficient/flexible resource management. Nevertheless, the main drawback of OFDM is the spectral efficiency (SE) loss concerning the use of the CP. In order to overcome that problem, filter-bank based multi-carrier (FBMC) has recently been proposed.
