“…Different channel coding exist in the literature such as Hamming Walsh, turbo and Low-Density Parity Check (LDPC) codes. Complex codes may provide better performance but at the cost of high power consumption and long latency due to the decoding complexity such as LDPC [26]. Therefore, when considering applications for WSNs, simple but efficient codes are more interesting.…”

One of the main challenges of wireless sensor networks is to maintain sensor nodes alive as long as possible, and a lot of efforts are dedicated to enable energy efficient communications. Wake-Up Receivers (WuRs) represent a promising solution for reducing the power consumption of nodes by enabling asynchronous communications. However, to achieve an ultra-low power consumption, WuRs circuits are kept as simple as possible, inducing a low sensitivity and thus a short range communication. As channel coding improves sensitivity, we propose to take advantage of the computing capability of the WuRs to apply a specific channel coding. The novelty resides in applying Minimum Energy coding with an Early Shutdown (MEES) of WuRs based on On-Off Keying (OOK) detectors. Both theoretical derivations and Monte-Carlo simulations show that the proposed coding scheme improves the reliability. Moreover, Moreover, MEES has been implemented on a non-coherent WuR prototype, and it is shown through experimentation that WuR reliability can be raised up to 22% compared to uncoded communications. Moreover, both the energy consumption and the latency can be significantly decreased thanks to the shutdown mechanism of MEES.

“…In order to balance the absolute fairness of system users, the literature studied the resource allocation algorithm based on proportional fairness in downlink OFDMA system [24]. Through simulation analysis, multiple parameters of the system are studied and analyzed, and it is proved that the algorithm has good performance with a slight reduction in throughput and can effectively maintain system fairness [25]. Literature carried out research and analysis on weight and rate maximization.…”

Green energy-saving communication is one of the important research topics for the development of 5G technology. Under the premise of widespread distribution of intensive base stations, system resource allocation and energy efficiency optimization are the keys to improving system performance. Therefore, how to effectively control system energy consumption and resource allocation has become the key to whether 5G technology can achieve effective application effects. In order to improve the energy efficiency performance of the cross-layer broadband wireless communication network system, this study combines the analysis of the broadband wireless communication system to optimize the energy efficiency of the crosslayer wireless communication system. Simultaneously, with the help of resource allocation technology, this study optimizes the multi-user underlying transport layer of the FDD-OFDMA system. In addition, this study explores the most reasonable system resource allocation method and achieves reasonable resource allocation through the optimization of energy efficiency resources in massive MIMO-OFDMA downlink systems. Finally, this study sets up a controlled experiment to analyze the algorithm's energy efficiency performance. The research shows that the method proposed in this paper has certain effects and can provide a reference for subsequent related research.

“…However, the codeword length is finite in practical wireless communication scenarios. In order to obtain a decoding threshold well consistent with the waterfall-region performance of the simulated BER result, a finite-length binary codeword including both 0 and 1 bits is assumed in the proposed hierarchical EXIT algorithm, as in [55]- [57]. • In the standard EXIT analysis for the conventional BICM-ID systems, only one extrinsic MI I Ed and one a-priori MI I Ad can be obtained in each outer iteration.…”

As a typical example of bandwidth-efficient techniques, bit-interleaved coded modulation with iterative decoding (BICM-ID) provides desirable spectral efficiencies in various wireless communication scenarios. In this paper, we carry out a comprehensive investigation on tail-biting (TB) spatially coupled protograph (SC-P) low-density parity-check (LDPC) codes in BICM-ID systems. Specifically, we first develop a two-step design method to formulate a novel type of constellation mappers, referred to as labeling-bitpartial-match (LBPM) constellation mappers, for SC-P-based BICM-ID systems. The LBPM constellation mappers can be seamlessly combined with high-order modulations, such as M -ary phase-shift keying (PSK) and M -ary quadrature amplitude modulation (QAM). Furthermore, we conceive a new bit-level interleaving scheme, referred to as variable node matched mapping (VNMM) scheme, which can substantially exploit the structure feature of SC-P codes and the unequal protection-degree property of labeling bits to trigger the wave-like convergence for TB-SC-P codes. In addition, we propose a hierarchical extrinsic information transfer (EXIT) algorithm to predict the convergence performance (i.e., decoding thresholds) of the proposed SC-P-based BICM-ID systems. Theoretical analyses and simulation results illustrate that the LBPM-mapped SC-Pbased BICM-ID systems are remarkably superior to the state-ofthe-art mapped counterparts. Moreover, the proposed SC-P-based BICM-ID systems can achieve even better error performance with the aid of the VNMM scheme. As a consequence, the proposed LBPM constellation mappers and VNMM scheme make the SC-Pbased BICM-ID systems a favorable choice for the future-generation wireless communication systems.
