Although it aims to understand the channel condition and communication environment with sensing capability, it still requires sustainable high-data transmission with efficient spectrum usage. The in-band full-duplex (IBFD) system can be a possible solution to support high data transmission while increasing spectrum efficiency. Since IBFD has a self-interference issue, one of the significant factors that deteriorate its performance, we need to investigate possible solutions to resolve this matter. In this paper, we present an improved self-interference cancellation receiver with successive interference cancellation (SIC)-based channel estimation for the IBFD system. Since SIC aims to mitigate the multiple interference effects, our proposed algorithm applied SIC to the channel estimation for the performance gain. Our results show that SI cancellation with SIC-based channel estimation improves the IBFD bit error rate (BER) of the new radio (NR) for the ISAC system.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"26 5","pages":"521-532"},"PeriodicalIF":2.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10748583","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600163","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}

Unaffected UEs are utilized as reference anchor nodes to position UAV-BS to a near optimal location. Studying UAV deployment in environments where GPS access in unavailable is crucial due to the susceptibility of UAVs to GPS jamming, which poses a potential risk of inaccuracy for ISAC systems. We jointly optimize UAV-BS communication performance and localization accuracy in terms of transmission power, root mean square error (RMSE), and position dilution of precision (PDOP). Further, we introduce three different algorithms to select the optimal set of reference nodes for accurate UAV-BS localization. Nodes are selected based on relative UE positions and different geometric configurations they form. Simulation is conducted for different UE distribution scenarios and results confirm that our proposed scheme can optimize the communication power and localization performance of UAV-BS under different PDOP constraints.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"26 5","pages":"490-501"},"PeriodicalIF":2.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10748594","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600418","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}

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.

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}
