This study addressed the communication and perception challenges posed by the complexity and variability of the marine environment and the mobility of ships, aiming to improve the performance of offshore operations. Through the construction of an integrated ship-based station model at the power level and comprehensive data validation and simulation analyses, this study revealed a linear relationship between the signal-to-noise ratio (SCNR) and the probability of detection, indicating that the probability of detection positively correlated with the SCNR. In practical multi-user scenarios, the shipborne ISAC base station needed to make a trade-off between communication and sensing functions to meet different SCNR requirements. By optimising the trajectory and power allocation of shipborne ISAC, this study successfully improved the communication rate and sensing performance, which further enhances the efficiency and safety of marine operations. The findings of this study were of great significance to the advancement of marine science and technology, laying a solid foundation for further research and the application of maritime communication networks.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"26 5","pages":"566-576"},"PeriodicalIF":2.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10748586","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unmanned aerial vehicles (UAVs) are essential for their flexible deployment, wide coverage, and high mobility. However, these attributes pose challenges for channel research. This paper presents a novel physical communication model for 6G ISAC in multiple-input multiple-output (MIMO) air-to-ground wireless channels. Here, the direct propagation link between the UAV transmitter and vehicle receiver is obstructed by buildings, hindering successful signal transmission. To address this, we propose employing double intelligent reflecting surfaces (IRSs) to assist signal transmission, forming the propagation links with either double or single IRSs along with the non-line-of-sight (NLoS) path. We investigate the complex channel impulse responses (CIRs) of these links considering multipath effects and derive the complete channel matrix. Additionally, we analyze the statistical properties of the communication model across various parameters. Leveraging these derivations, we illustrate the propagation characteristics of the MIMO UAV-to-vehicle communication model empowered by double IRSs. Simulation results highlight the superior channel characteristics of double- IRSs compared to single-IRSs, underscoring the significance of integrating double IRSs into the UAV-to-vehicle channel model.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"26 5","pages":"509-520"},"PeriodicalIF":2.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10748578","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, by taking advantage of frequency diverse array (FDA), which can generate beampatterns in angle, range and time domains, we propose a novel finite orthogonal random FDA, whose beampatterns feature periodical pulses in time or range domain. By applying this technology into radar and communications (RadComm) systems, a compact dual-functional structure of joint PA and FDA is designed. With the proposed novel structure, the common information, such as channel status information and direction-of-arrival can be easily shared for both PA communications and FDA radar. Based on the built joint PA and FDA channel models, different beamformer designs are proposed by jointly optimizing the signal-to-interference- noises of the communications and radar. In addition, we robustify the proposed method by considering the case of channel estimation imprecision. Numerical simulations demonstrate the performances of both communications and the radar with the proposed approaches are over than that of the conventional PA RadComm systems.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"26 5","pages":"554-565"},"PeriodicalIF":2.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10748579","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the high computation complexity of maximum likelihood (ML) multi-user detection, a low complexity multi-path successive interference cancellation (MSIC) multi-user detector is introduced to achieve near-ML detector's block error ratio (BLER) performance. Furthermore, considering that each user is only concerned with their own transmitted signal in the downlink GMUSST system, we propose a minimum mean square error-based SIC (MMSE-SIC) detector, which can directly extract the user's transmission signal from the received superimposed signal of multiple users and is verified compared with MSIC detector. Simulation results show that the GMUSST can achieve better transmission reliability than the existing polar coded sparse code multiple access (PC-SCMA) in the short packet communication scenarios. Especially with the hybrid automatic repeat request mechanism, GMUSST requires fewer retransmissions to achieve the same BLER performance compared to PC-SCMA.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"26 4","pages":"433-444"},"PeriodicalIF":2.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10666071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we go one step further by considering ensembles of LDPC codes with degree-degree correlations. We propose two methods to construct such an ensemble of degree-degree correlated LDPC codes and derive a system of density evolution equations for these codes over a binary erasure channel (BEC). By conducting extensive numerical experiments, we demonstrate how the degree-degree correlation affects the performance of LDPC codes. Our numerical results suggest that LDPC codes with negative degree-degree correlation could enhance the maximum tolerable erasure probability. Moreover, increasing the negative degree-degree correlation could facilitate better unequal error protection (UEP) design. In the final part of our extension efforts, we extend degree-degree correlated LDPC codes to multi-edge type LDPC codes and leverage these to construct convolutional LDPC codes.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"26 4","pages":"1-15"},"PeriodicalIF":2.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10666064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
