Next-Generation Passive Optical Network Based on Sparse Code Multiple Access and Graph Neural Networks

Sparse code multiple access (SCMA) is a promising technology to provide high throughput and overall improved system performance at affordable cost for next-generation passive optical networks (NG-PONs). Message passing algorithm (MPA) based on a factor graph is usually used for low-complexity multi-...
