However, practical signal recognition scenarios often face a shortage of labeled samples and an abundance of unlabeled ones. Therefore, semi-supervised learning (SSL) methods have emerged as a solution. This letter proposes a novel signal-understanding semi-supervised learning (SUSSL) framework to enhance the performance of SSL further. SUSSL comprises a reconstruction and a metric module. The former module learns useful features by disrupting and reconstructing low-level features, and the latter utilizes similarity learning to process low-level features. A symmetric dual-branch neural network (SDNN) model is also designed to facilitate these two modules. Simulation experiments on the open-source datasets RadioML2016.10a and RadioML2016.10b demonstrate that the proposed method outperforms current SSL methods.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"28 12","pages":"2789-2793"},"PeriodicalIF":3.7,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the presented system model, a full-duplex base station communicates with downlink and uplink communication users and simultaneously performs mono-static sensing of a target. The performance of this system is evaluated by analytically deriving the closed-form expressions of ergodic rate in the presence and absence of a target. Despite co-channel interferences and the presence of the target, NOMA achieves a significantly better rate, thus improving the system’s performance and making it a suitable technology for ISAC systems. The derived analytical results for a Rayleigh fading are verified and are in exact agreement with Monte-Carlo simulations. Further, more insights have been obtained by comparing the performance results of the considered system model with that of a traditional orthogonal multiple access scheme.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"28 12","pages":"2774-2778"},"PeriodicalIF":3.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extremely high spectral efficiency of OAM is crucial for meeting future wireless communication demands. However, OAM-based wireless communication faces a significant challenge known as the hollow divergence effect, which reduces received power and signal integrity. This letter proposes a method to focus the OAM beam using the transmitting array to eliminate the divergence. Our proposed method generates an approximate ideal OAM (A-OAM) beam within a specific tolerance range around the receiver. Compared to traditional diverging OAM (D-OAM), the A-OAM beam does not diverge within its tolerance range. Specifically, we first propose the focusing method and system model for A-OAM by investigating its propagation characteristics. Then, we evaluate the focusing method through simulations ranging from 6 to 14 metres. The results are consistent with our theoretical expectations. A-OAM enables the simultaneous reception of multiple OAM modes over long distances, significantly enhancing the robustness of OAM-based wireless communication.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"28 12","pages":"2899-2903"},"PeriodicalIF":3.7,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach is designed for a scenario where a single UAV is responsible for collecting data from multiple ground sensors, while encountering multi-jammers from a ground-based adversary. The objective is to maximize the average data rate of all sensors while ensuring a sufficient amount of data is collected from each sensor. The optimization problem is formulated as a mixed-integer non-convex problem, and successive convex approximation(SCA) technique is employed, which jointly optimizes the collection schedule, power control and UAV trajectory. Numerical simulations demonstrate that the proposed approach outperforms in the presence of interference and imperfect CSI.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"28 12","pages":"2839-2843"},"PeriodicalIF":3.7,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this letter, we investigate a simultaneous wireless information and power transfer (SWIPT) system with non-orthogonal multiple access (NOMA) assisted by CPS-STAR-RIS. To maximize the average sum-rate (ASR) of the system, we propose an alternating optimization (AO) scheme to jointly optimize the active beamforming vectors at the base station (BS) and the transmission and reflection coefficients at the CPS-STAR-RIS. Specifically, we first equivalently represent the ASR maximization problem by applying the weighted minimum mean square error (WMMSE) algorithm to address the coupling of variables. Subsequently, the successive convex approximation (SCA) algorithm and the penalty dual decomposition (PDD) algorithm are adopted to tackle the optimization challenges of the active beamforming vectors at the BS and the coefficients at the CPS-STAR-RIS, respectively. Simulations show that compared with the conventional RIS (CRIS) and the OMA schemes, the proposed scheme significantly enhances the ASR.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"28 12","pages":"2889-2893"},"PeriodicalIF":3.7,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
