Nevertheless, detecting small targets is highly challenging due to their minimal pixel presence in images, indistinct features, and complex backgrounds. Existing detection methods are often interfered by complex backgrounds, resulting in unsatisfactory detection results. To overcome this challenge, this study introduces the mixture of experts infrared small target detection (MOE-IR) method. The core idea of this method is to construct a mixture of experts feature extraction network to perform rich feature extraction and complex background suppression on small targets, respectively, so as to achieve robust infrared small target detection in complex backgrounds. Specifically, the MOE-IR comprises a target feature extraction expert and a background suppression expert. The target feature extraction expert focuses on enhancing the features of infrared small targets, while the background suppression expert aims to mitigate background clutter. Additionally, an adaptive gate controlled network is incorporated to dynamically assign weights to the two experts based on the input infrared image, ensuring effective detection of infrared small targets across diverse and complex scenarios. Extensive experiments demonstrate that the proposed algorithm surpasses existing infrared small target detection methods in terms of detection accuracy and false alarm rate. It can reliably and stably identify small targets within infrared images, thus offering an effective solution for practical infrared small target detection applications.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70359","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635085","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}

However, due to the ever-growing complexity of the electromagnetic environment, traditional broadband detection algorithms are no longer suitable for current application needs. This paper proposes a broadband signal detection model, NLYOLO. We improve the precision of the image by analysing the characteristics of the target signal by selecting suitable parameters. We also select anchors adapted to the special shape of the target signals and introduce attention modules Non-local and SimAM in the feature extraction of NLYOLO and improve the loss function. This enhances the ability of high-level semantic information feature extraction and improves the precision rate and recall of small target signals. The experimental results show that compared with the traditional energy detection algorithm and the baseline model, the detection precision and recall rate are significantly improved, which effectively achieves the target detection task in the field of signal processing in complex scenes.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70358","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598541","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}

The system leverages high-impedance dipole (HID) as Txs to dynamically activate the nearest Tx to a simple dipole antenna as the Rx while deactivating other Txs without additional control circuits. The Txs design incorporates a modified coaxial cable dipole antenna featuring symmetrical gaps over the shield and inductive tuning elements between the central wire and the shield to optimise the resonance frequency and ensure effective power transfer. The feeding point is connected to the central wire via a small cut in the shield. This autonomous behaviour simplifies system operation, enhances flexibility, and ensures acceptable efficient power transfer. Experimental evaluation demonstrates that the system achieves a power transfer efficiency of approximately 65% while maintaining consistent performance as the Rx rotates over two orthogonally located Txs. The dynamic self-tuning mechanism adapts to the position of the Rx, proving particularly advantageous on curved surfaces.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70339","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582131","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}

In this letter, we propose a novel dynamic resource reservation scheme for distributed admission control. It uses information available in distributed networks to adaptively adjust local deadlines and bandwidth reservations in response to dynamic traffic changes, ensuring end-to-end deadlines for time-critical traffic while maximizing available bandwidth for non-time-critical traffic. We also present the implementation within the resource allocation protocol (RAP) model, eliminating the need for centralized storage and decision-making. Experimental results show that our method avoids the need for pre-configuration based on prior traffic knowledge, increases admissions for time-critical traffic, and enhances available bandwidth for non-time-critical traffic.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70350","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144581846","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}
