Advanced Television Systems Committee (ATSC) 3.0, which is the new international standard for next generation broadcasting, allows to deliver multiple services with different reception conditions in a single RF channel. 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 this paper, we consider two services configured by LDM and TDM based on the ATSC 3.0 standard. Field test results which evaluate the mobile performance of LDM and TDM are provided.
