“…The modern ATSC 3.0 recommends the use of the LDM modulation technique. Therefore, several articles were published with studies concerning the capacity of LDM in ATSC 3.0 [39], memory use aspects for the LDM technique in the system [40], MIMO schemes utilization [41], field tests [42], studies about efficient schemes for decoding and LDPC application [43][44][45], performance analysis for mobile services [46], among others.…”

This paper presents an implementation of a 3layer transmitter and receiver using Layer Division Multiplexing (LDM), in Software Defined Radio (SDR). The main idea of this work is to show another point of view of the traditional LDM technique that uses two layers. This proposal uses an attenuated intermediate layer, called Middle Layer (ML), between the highest power layer, called Upper Layer (UL), and the most attenuated layer, called Lower Layer (LL). The UL is fully compatible with the Integrated Services Digital Broadcasting Terrestrial -Version B (ISDB-T B ). The ML, with greater robustness, and LL, with higher capacity, use powerful channel coders, a custom frame size and an adapted bit interleaver. With the use of this modified LDM, it is possible to develop a system with different robustness levels between layers and with lower layers that complement each other, to achieve bit rates that allow for the deployment of High Definition Television (HDTV), in the UL, and Ultra High Definition Television (UHDTV), in the ML and LL. In addition, a system was also implemented with three layers, but with the ML with higher capacity and the LL with greater robustness. The performance of the 3-layer system was compared with the 2-layer LDM technique and there was an improvement in the system modularity, without a decrease in the bit rate.

“…They present two differ-ent structures of LDPC codes in the ATSC 3.0 standard in including television broadcasting. In [109], a low-complexity decoding scheme of LDPC codes for the layered-division multiplexing (LDM) systems in ATSC 3.0 is proposed. The signals of next-generation digital television terrestrial broadcasting systems can play vital roles for an experimental study of machine learningbased localization schemes [110] and in the basic workflow to explain how to apply machine learning technology in the networking domain [111].…”

We expose a complete survey of error-correcting codes (ECC) for digital video broadcasting (DVB) to support information protection. This survey discusses the specific application of the adaptive ECC feature for terrestrial/satellite/handheld and cable of the first, second, and third generations. We provide and review an ECC technique overview on DVB standard with their technical transmission specifications. The critical contribution of this paper is to clarify the differences among different ECC technologies using in the three generations of DVB. The survey also provides future directions for the technology trend of ECC for DVB.
