In the physical layer standard of ATSC 3.0, two kind of multiplexing schemes are adopted: orthogonal schemes including traditional time division multiplexing (TDM) and frequency division multiplexing (FDM), and a newly introduced non-orthogonal scheme, named layered division multiplexing (LDM). In ...

Transmission is the method by which computer networks send electrical signals. Data communication is concerned with the process of exchanging data electronically between two communication devices. In a local area network, all communication functions perf
Frequency division multiplexing (FDM) and multi-carrier technologies are some examples of this kind of scheme. Spacial. This scheme consists of spatially separating the resources considering their coverage area forming clusters, cells, or sectors coverage to allow their reuse. These schemes are widely...
