In this paper, a power sparse code division non-orthogonal multiple access (PSCD-NOMA) scheme is proposed for next-generation flexible optical access, which is based on the multi-stack network. All ...

Optical Code Division Multiple Access (OCDMA) systems represent a cutting‐edge approach to broadband communications, enabling simultaneous data transmission from multiple users over a single ...

In this paper, the transform domain code division multiple access (TDCDMA) is proposed, which synthesizes the excellence of the transform domain communication system (TDCS) and the code division ...
