More Information
Summary:Subcarrier multiple access (SCMA) is described. It is a flexible access technique for passive optical networks (PONs), both for fiber-to-the home and fiber-to-the curb architectures. The main advantages of SCMA are the independence of the channels, which yields flexibility with respect to modulation format and evolution scenario, and the absence of synchronization between the different subscribers. Some results of SCMA experiments are presented. The capability of broadband channels is discussed, taking into account the optical interference effect. A comparison is made with other access techniques.< >
