Study on 4-Layer Layered Division Multiplexing using ATSC 3.0 Broadcasting System

This paper presents 4-layer(4L) Layered Division Multiplexing(LDM) using ATSC 3.0. The studies on 4L LDM with PN sequences and on 4L LDM with QPSK are conducted by applying PN sequences and QPSK as the 4th layer in 3-layer(3L) LDM with amplitude shift keying respectively. In the previous researches, 4L LDM with PN sequences using DVB-T2 was conducted and its bit error rate(BER) analysis was performed. We conduct studies on 4L LDM with PN sequences using ATSC 3.0 and present its BER analyses as subsequent researches of 4L DLM with PN sequences using DVB-T2. Additionally, we conduct researches on 4L LDM with QPSK as the 4th layer and present its BER analyses.
