“…In this survey, we focus on the ECCs of the first and second generation of the European standard DVB-T/C/H and DVB-T2 whose concatenated codes do not differ from other standards. Because the Subcarrier spacing in SFN varies from that in narrowband [38,39], the DVB-T often needs MER for OFDM signal performance in SFN.…”

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.

“…Upon deployed, every node broadcasts a small interest message to identify its neighbours and path to the BS as guided by the Friis transmission equation. It is also important to mention that the Meshnet is the most preferred deployment approach for the NB-IoT networks [ 57 , 58 ]. This is due to the self-forming and self-healing nature of Mesh Networks which presents the following advantages when used for NB-IoT systems: Better efficiency: With its ability to quickly create robust ad-hoc networks, mesh technology is proven to be a high-performance data transfer solution which happens to be the core of most NB-IoT applications (example of Wireless Sensor smart metering NB-IoT networks and many more).…”

Most of the current research work on the Narrowband Internet of Things (NB-IoT) is focused on enhancing its network coverage. Many of the existing NB-IoT channel coding techniques are based on repeating transmission data and control signals as a way of enhancing the network’s reliability and therefore, enabling long-distance transmissions. Although most of these efforts are made at the expense of reducing the energy consumption of the NB-IoT network, they do not always consider the channel conditions. Therefore, this work proposes a novel NB-IoT Energy-Efficient Adaptive Channel Coding (EEACC) scheme. The EEACC approach is a two-dimensional (2D) approach which not only selects an appropriate channel coding scheme based on the estimated channel conditions (dynamically classified as bad, medium or good from initial based on a periodically assessed BLER performance outcome) but also minimizes the transmission repetition number under a pre-assessed probability of successful transmission (based on the ratio of previous successful transmissions over the total number of transmissions). This results in creating a single mixed gradient based on which a higher or lower Modulating Coding Scheme (MCS) is selected on each transmission. It is aimed at enhancing the overall energy efficiency of the network by dynamically selecting the appropriate Modulation Coding Scheme (MCS) number and efficiently minimizing the transmission repetition number. Link-level simulations are performed under different channel conditions (good, medium, or bad) considerations to assess the performance of the proposed up-link adaptation technique for NB-IoT. The obtained results demonstrate that the proposed technique outperforms the existing Narrowband Link Adaptation (NBLA) as well as the traditional repetition schemes in terms of the achieved energy efficiency as well as network reliability, latency, and scalability.

“…However, as mentioned previously, correcting errors with the minimum number of retransmissions can improve the error rate by using different methods in a different context, as described in [23]. Therefore, in this study, we focused on a specific subcarrier technology [11] with a precisely selected SCS. We recommend the incorporation of this technique to the slave station's IoT remote terminal unit (RTU), to ensure a low rate and relatively low power consumption scenario.…”

In this study, a narrowband (NB) internet of things (IoT) medical device (MD) wireless communication system was established, in which a multi-hop source to the MD network shared the downlink and uplink resources to probe and control the MDs of hospital patients. A multicast data packet was distributed over the multi-hop MD networks, and a random linear network coding approach was applied in the source instead of the intermediate nodes. We evaluated the MD probe cycle between a master station and remote terminal units, which were connected with several critical devices in a medical room. Furthermore, an accelerated end-to-end (E2E) probing protocol was established in the wireless mesh network to minimize the probing cycle of the health devices. In particular, a faster protocol was developed to address the probe and control subproblem. The proposed approach could assist in realizing the accelerated E2E probing for NB-IoT MDs, reducing the number of retransmissions, recovering lost packets, and providing a prompt overview of the medical network performance, based on several basic parameters. Furthermore, in a comparative study of the contemporary probing cycle techniques, the proposed protocol notably outperformed several widely used protocols, with the improvements typically exceeding 71% and 60%, respectively.
