As an advanced technology, digital twin (DT) maps physical entities into virtual domain, enables real-time monitoring and dynamic updates, thereby enhancing the adaptability and performance of multi-UAV networks. In this letter, we investigate joint spectrum allocation and power control for a multi-UAV radar sensing network, where multiple unmanned aerial vehicles (UAVs) simultaneously perform radar sensing separately to detect targets and avoid collision. By modeling the multi-UAV network as a graph, we employ graph neural network (GNN) to capture environmental features, construct the DT network, and address resource allocation issues. In particular, we propose a message-passing neural network based spectrum allocation method and a graph attention network based power control method to maximizing the minimum radar echo signal-to-interference-plus-noise ratio (SINR) among all UAVs. Simulation results show that the proposed DT-enhanced GNN based resource allocation method can significantly improve the minimum SINR and extend the sensing coverage.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"13 11","pages":"3137-3141"},"PeriodicalIF":4.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160484","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}

A new technology, intelligent reflecting surfaces (IRS), has been recently introduced, offering a way to control and steer light propagation in VLC systems. This letter proposes an innovative approach for enhancing the physical layer security (PLS) in IRS-assisted VLC by utilising the effect of the time delay induced by the IRS reflections. More specifically, we consider how to allocate the IRS elements in a way that produces destructive intersymbol interference at the eavesdropper’s location while enhancing the signal reception at the legitimate user. Our results show that, at a fixed light-emitting diode power of 3W, the secrecy capacity can be enhanced by up to 253% at random positions for the legitimate user when the eavesdropper is located within a 1-meter radius of the LED. We show that careful IRS allocation can lead to enhanced PLS even when the eavesdropper has a more favorable position than the legitimate user.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"13 11","pages":"3147-3151"},"PeriodicalIF":4.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160485","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}

To secure the privacy of served users from malicious targets, artificial noise (AN) carrying no information is often transmitted in conventional security schemes. In this letter, we propose to employ multicast signals to convey group-oriented information to cooperative targets, disrupt malicious targets, and simultaneously sense all targets. Meanwhile, unicast signals are transmitted for privacy information of the served users. We formulate a robust secure beamforming problem that deals with imperfect channel state information (CSI) and the uncertainty regarding the angles of malicious targets. To solve this problem, we propose a penalty-based iterative algorithm by transforming the non-convex optimization problem into a convex one with semidefinite relaxation (SDR) and examining the relationship between the trace, the largest eigenvalue and the rank of a positive semidefinite matrix. Numerical results are provided to demonstrate that, with lower computational complexity, the proposed scheme delivers superior performance, compared to state-of-the-art schemes.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"13 10","pages":"2927-2931"},"PeriodicalIF":4.6,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137921","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}

These advantages are established based on accurate channel state information (CSI) at the base station (BS), which comes with a very high cost due to continuous CSI feedback from all the user equipments (UEs). In this letter, we propose a neural network-based CSI compression scheme with simple encoder-decoder framework for mMIMO systems. To achieve high accuracy, our proposed framework constructs an overall perceptual encoder-decoder structure with holistic cross-joint convolution (HCC) modules of different scales. In addition, a perceptual loss is introduced into the proposed design to further improve the accuracy in matrix recovery and limits the computational cost. Substantial experimental results demonstrate that the proposed HCC network (HCC-Net) is superior to several advanced algorithms in terms of estimation accuracy and computational complexity, such as the CSiNet+ and TransNet.","PeriodicalId":13343,"journal":{"name":"IEEE Wireless Communications Letters","volume":"13 10","pages":"2937-2941"},"PeriodicalIF":4.6,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137920","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}
