“…Moreover, in [85], a performance comparison was conducted between Layered Division Multiplexing (LDM) and Time Division Multiplexing (TDM) based mobile delivery over ATSC 3.0, showing through simulation that compared to TDM, LDM can significantly lower the SINR reception threshold for the same rate especially at high speeds. The community is focusing now on finishing the work of important elements of the system so the mass implementation could start [86].…”

“…Consider a typical application scenario of LDM where there are two differentiated services, namely mobile services and fixed services. The former is used for outdoor and portable reception of high-definition signals, which can usually tolerate lower data rates and is carried by the more robust CL; the latter is exploited to transmit ultra-high-definition television signals, which usually require higher data rates and are carried by the lower power EL [ 21 , 22 , 23 , 24 , 25 ].…”

In the traditional layered division multiplexing (LDM) system, by simply adjusting the injection level, the reception performance of the core layer (CL) mobile services will be decreased significantly, resulting in the deterioration of system coverage performance. Thus, it is necessary to improve the performance of the enhanced layer (EL) service reception without affecting the reception threshold of CL service. To achieve this, in this paper, an enhanced LDM (En-LDM) scheme that supports multi-service transmission is proposed for the next-generation broadcasting network. In this scheme, at the transmitter end, part of the low-density parity-check (LDPC) coded data stream of fixed service conveyed in the EL will be extracted out through puncturing, and then, it will be transmitted over the CL of the LDM signal along with the original CL data in a frequency domain multiplexing (FDM) manner. At the receiving end, the punctured data of the EL fixed service will be recovered with a higher signal-to-noise ratio (SNR). Compared to the traditional LDM scheme, the proposed En-LDM scheme can significantly improve the reception performance of fixed services without decreasing the SNR threshold of mobile services. Moreover, the En-LDM can achieve a higher channel capacity than that of the traditional LDM for both the fixed services and the overall services. The superiority of the proposed En-LDM scheme over the traditional LDM scheme is validated by the simulation under the additive white Gaussian noise (AWGN) and fading channels.

“…In July 2015, digital terrestrial television multimedia broadcasting-advanced (DTMB-A), China's next-generation digital television broadcasting system was officially adopted by the International Telecommunication Union (ITU) as the international standard [3]. In September 2016, the American next-generation terrestrial broadcasting system Advanced Television System Committee (ATSC) 3.0 physical layer standard was released [4]. It is worth pointing out that DVB-T2, DTMB-A, and ATSC 3.0 all support 4K UHDTV and are suitable for multi-service transmission of both mobile and fixed services [4][5][6].…”

In order to improve system coverage performance, in this paper, a multi-service transmission scheme on the basis of the puncturing technique, namely layered division multiplexing extension frequency-division multiplexing (LDM-Ex-FDM), is proposed. The key idea of the proposed scheme is that the symbols punctured from the enhanced layer (EL) of fixed services will be independently transmitted on a certain number of subcarriers orthogonal to the LDM signal of the core layer (CL) and most of the EL. By doing so, the punctured symbols will be demodulated with a higher signal-to-noise ratio (SNR) on the receiver side and can be recovered well, thus improving the reception performance of the EL fixed services. Moreover, two puncturing strategies based on bit-interleaved coded modulation (BICM) symbols of the LDM-Ex-FDM scheme, namely equal interval symbol puncturing (EISP) and non-equal interval symbol puncturing (NEISP), are developed to improve the performance of the EL services. Simulation results are given to show that, when the puncturing rate in the LDM-Ex-FDM scheme is configured as 1/12, the performance of the fixed service can be improved by 1.8 dB, meanwhile the bit error rate (BER) performance of the mobile service is not affected. Thus, the overall system coverage performance can be improved. Furthermore, to reduce the computational complexity and the demodulation delay of fixed service carried in the EL, at the receiver, a direct interference cancellation (DIC) detector is proposed as well. Simulation results are given to show that, under high injection level and high modulation order, the proposed DIC scheme is able to achieve almost the same BER performance as that of the traditional successive interference cancellation (SIC) scheme while with lower computational complexity.
