Specifically, an integrated radar and communication platform (IRCP) equipped with full-dimensional antenna arrays can execute 3D beamforming, which can effectively minimize interference for communicating with unmanned aerial vehicles (UAVs). However, a significant challenge in fully exploiting 3D beamforming gain is the IRCP's ability to precisely track manoeuvrable UAVs. In this letter, we propose a novel interacting multiple model with enhanced unscented Kalman filter algorithm to realize 3D beam tracking for one manoeuvrable UAV within the framework of DFRC. To be specific, we build multiple state transition models to adopt the manoeuvrability of the UAV. Meanwhile, the stability of the unscented Kalman filter is improved by using the singular value decomposition. Simulation results show that the proposed algorithm has higher tracking accuracy and better transmission performance for one manoeuvrable UAV than the traditional single-motion model based beam tracking algorithm.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70211","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore this potential, we propose a quantum communication system for image transmission, addressing the challenges of transmitting high-quality image data over error-prone channels. A crucial aspect of advancing this field is quantum channel coding, specific to quantum systems. Therefore, this research evaluates the performance of low-complex three-qubit quantum error correction code for image transmission over noisy channels. JPEG and HEIF images are encoded using three-qubit error correction method and compared to 1/3 rate polar codes with equivalent bandwidth. Results show that the three-qubit error correction code significantly outperforms advanced classical polar codes in both classical and quantum domains, achieving a maximum PSNR of 64.5 dB (SSIM = 0.9997) in HEIF and 58.3 dB (SSIM = 0.9994) in JPEG. These findings underscore its potential as a robust solution for quantum communication in media transmission.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70205","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous works have either excluded UL communication, avoiding the interference it introduces to DL communications and target detection, or have used the beam pattern gain as the radar performance metric in the objective function. In contrast, two optimization problems are proposed for the FD-ISAC BS that address these challenges. One is based on CU sum rate maximization subject to radar performance, and the other is based on the received radar SINR maximization subject to CUs' performance. The high complexity of the problems is tackled by applying the concave–convex procedure and quadratic transformation to the two proposed formulations, respectively. Finally, simulation results are provided under a single cell setup to illustrate the effectiveness of the proposed algorithms which converge within three to four iterations. In addition, the sum rate of the CUs and radar SINR showed doubled improvements compared to the baseline half-duplex schemes.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70138","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the recent surge in online media consumption, users are increasingly demanding immersive and vivid visual experiences through realistic content. Stereoscopic 3D media content, in particular, offers users a sense of depth and immersion that provides a viewing experience unparalleled by traditional 2D content. In this paper, we propose a web playback framework that applies scalable encoding technology, demonstrating its ability to deliver high-resolution 3D media content in a stable and consistent manner within web environments. Experimental results show that the proposed scalable 3D media web playback framework (S3WPF) can successfully stream stereoscopic 3D media content at 1920 × 1080 resolution and 30fps in real-time across various web environments. This confirms the framework's practicality and commercial viability, as it meets the quality level required for commercial OTT services.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70200","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the inherent large time-bandwidth product associated with SFW results in significant ranging errors and energy dispersion, impeding its effectiveness in detecting high-speed targets. Spurred by this limitation, this study introduces an innovative velocity estimation method that employs the fractional Fourier transform (FrFT) to overcome these drawbacks. Specifically, by harnessing the Doppler signature of a moving target, which appears as a chirp signal with a frequency rate directly proportional to the target's velocity, FrFT provides precise velocity measurements. Following the velocity estimation, a compensation process is implemented using the derived metrics, after which the inverse fast Fourier transform locates the target accurately. Furthermore, an iterative algorithm based on the golden section search technique has been developed to enhance the computational efficiency of determining the optimal order for the FrFT. The validity of the proposed method is confirmed through simulation data, demonstrating that the developed approach can accurately estimate the velocity of high-speed targets with a notably reduced computational complexity.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70096","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
