Domain Adaptation for DoA Estimation in Multipath Channels with Interferences

We consider the problem of estimating the direction-of-arrival (DoA) of a desired source located in a known region of interest in the presence of interfering sources and multipath. We propose an approach that precedes the DoA estimation and relies on generating a set of reference steering vectors. The steering vectors' generative model is a free space model, which is beneficial for many DoA estimation algorithms. The set of reference steering vectors is then used to compute a function that maps the received signals from the adverse environment to a reference domain free from interfering sources and multipath. We show theoretically and empirically that the proposed map, which is analogous to domain adaption, improves DoA estimation by mitigating interference and multipath effects. Specifically, we demonstrate a substantial improvement in accuracy when the proposed approach is applied before three commonly used beamformers: the delay-and-sum (DS), the minimum variance distortionless response (MVDR), and the Multiple Signal Classification (MUSIC).

Cloud-based RFID is gaining popularity in tandem with the growth of cloud computing and the Internet of Things (IoT). The cloud-based RFID system is developed with the intent of providing real-time data that can be sent into the cloud for easy access and interpretation. The security and privacy of constrained devices in these systems is a challenging issues for many applications. To deal with this problem, we first introduce χ per, as a new hardware/software friendly component that can be implemented using bit-wise operations and extensively analyze its security. Next, we propose χ perbp, a lightweight authentication protocol based on χ per component. To evaluate the performance efficiency of our proposed scheme, we implement the χ perbp scheme on an FPGA module Xilinx Kintex-7 using the hardware description language VHDL. Our security and cost analysis of the proposed protocol shows that the proposed protocol provides desired security against various attacks, at a reasonable cost. Also, formal security evaluation using BAN logic and the Scyther tool indicates its security correctness. Besides, we analyze the security of a related protocol which has been recently proposed by Fan et al. It is a cloud-based lightweight mutual authentication protocol for RFID devices in an IoT system. The authors have claimed that their scheme is secure against active and passive attacks, however, our detailed security analysis in this paper demonstrates the major drawbacks of this protocol. More precisely, the proposed attack discloses the tag’s secrets efficiently. Given the tag’s secrets, any other attack will be trivial. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Riemannian Covariance Fitting for Direction-of-Arrival Estimation

arXiv

引用

arXiv 2024年

作者： Picard, Joseph S. Bar, Amitay Talmon, Ronen The Viterbi Faculty of Electrical and Computer Engineering Technion - Israel Institute of Technology Haifa32000 Israel

Covariance fitting (CF) is a comprehensive approach for direction of arrival (DoA) estimation, consolidating many common solutions. Standard practice is to use Euclidean criteria for CF, disregarding the intrinsic Hermitian positive-definite (HPD) geometry of the spatial covariance matrices. We assert that this oversight leads to inherent limitations. In this paper, as a remedy, we present a comprehensive study of the use of various Riemannian metrics of HPD matrices in CF. We focus on the advantages of the Affine-Invariant (AI) and the Log-Euclidean (LE) Riemannian metrics. Consequently, we propose a new practical beamformer based on the LE metric and derive analytically its spatial characteristics, such as the beamwidth and sidelobe attenuation, under noisy conditions. Comparing these features to classical beamformers shows significant advantage. In addition, we demonstrate, both theoretically and experimentally, the LE beamformer’s robustness in scenarios with small sample sizes and in the presence of noise, interference, and multipath channels.

The traditional recognition methods of wheel hubs are mainly based on extracted feature matching. In practical production, their accuracy, robustness and processing speed are usually greatly affected. To overcome these problems, this paper proposes a recognition method based on convolutional neural network. The basic steps include two parts: wheel image pre-processing and wheel model classification. The image processing method, mainly using the detection algorithm of hough circles, obtains the center coordinates and radius of the wheel. Then it maps the ring-shaped wheel in right-angle coordinates to polar coordinates by the center coordinates and radius. This stepcan extract the ring-shaped feature information of the wheel image and reduce the influence generated by redundant features. Then a network architecture with an improved Resnet is designed to classify the wheel models. Finally, the wheel model recognition algorithm is evaluated, and the effectiveness of the method is verified through the comparison experiments of SVM, KNN and other models. The experiments show that the recognition accuracy can reach about 99.8% for 10 kinds of wheels. © 2023 IEEE.

Lithium-ion batteries are widely applied in sustainable energy conversion system. Consequently, it is of great research significance to accurately estimate the state of health (SOH) of batteries. To effectively model the input features at the spatial level, this article proposes a self-attention graph pooling convolutional network (SAGPCN) to estimate the SOH. The advantages of SAGPCN proposed in this paper can be reflected as follows: (1) The SAGPCN can consider node characteristics and graph topology, which focuses the attention on key parts of the graph. (2) The SAGPCN designs a self-attention mechanism to reserve significant nodes and delete secondary nodes, so as to optimize the network structure. A real-world dataset is adopted to evaluate the proposed battery SOH estimation approach in this paper. Experimental results represent that the estimation performance of the proposed SAGPCN is better than some data-driven SOH prediction approaches. © 2023 IEEE.
