“…In [7], energy detectors were proposed for orthogonalfrequency-division-multiplexing signals. In [8], the physical layer security of ambient backscatter with hardware impairment was investigated. In [9], energy and maximum likelihood detectors were proposed and analyzed using Gaussian approximation.…”

Reconfigurable intelligent surface (RIS) has been proved effective in improving the performance of communications. In this letter, the effect of RIS on individual links in ambient backscatter communications is examined. The average bit error rate is derived for the cases when the source-to-reader (S-R) link, the source-to-tag (S-T) link, or both S-R and S-T links use RIS to enhance their links. Numerical results show that generally speaking the performance of ambient backscatter communications degrades when the number of RIS elements in the S-R link increases, while improves when the number of RIS elements in the S-T link increases, when RIS is used to enhance the relevant link. Also, the two effects cancel out but in general the performance improves when both links are enhanced by RIS.

“…Unfortunately, between the satellite and the terrestrial terminal, masking effect caused by some obstacles and shadowing will make the line-of-sight (LOS) communication unstable even unavailable, and the performance of the satellite network will be affected seriously. Therefore, relay technology has drawn increasing attention by researchers due to its improvement in the reliability and coverage of the networks [4][5][6][7][8][9].…”

This paper explores the secrecy analysis of a multihop hybrid satellite-terrestrial relay network (HSTRN) with jamming, where one satellite source is aimed at communicating with destination users via multihop decode-and-forward (DF) terrestrial relays, in the existence of an eavesdropper. All the destination users are deployed randomly following a homogeneous Poisson point process (PPP) based on stochastic geometry. Each relay operates not only as a conventional DF relay to forward the received signal but also as a jammer to generate intentional interference to degrade the eavesdropper link, considering shadowed-Rician fading for legitimate link and wiretap link while Rayleigh fading for jamming link. To characterize the secrecy performance of the considered network, the accurate analytical expression for the secrecy outage probability (SOP) is derived. In order to reveal further insights on the achievable diversity order of the network, the asymptotic behavior of SOP expression at high signal-to-noise ratio (SNR) region is deduced. Moreover, the throughput of the system is discussed to characterize the secrecy performance. Finally, the theoretical results are validated through comparison with simulation results and show that (1) the secrecy performance of the considered network gets better with the decreasing of the hops and with the decreasing severity of the channel fading scenario, (2) the relay of the network operating as a jammer can provide better secrecy performance without extra network resources, and (3) small hops and high SNR can yield to high throughput of the system.

“…Global Navigation Satellite System (GNSS) has provided enough accuracy for outdoor positioning but not good indoor. 5G Internet of Things (IoT) is a popular research topic including various application scenarios such as indoor positioning, smart transportation, smart manufacturing, and smart security [1][2][3][4]. A variety of indoor positioning systems have emerged, including Ultra-Wide Band (UWB), Wi-Fi, Bluetooth, and Long-Term Evolution (LTE) [5][6][7].…”

Fingerprinting technique for indoor positioning based on 5G system has attracted attention. Kalman filter (KF) is used as preprocessing of raw data to reduce the disturbance of Received Signal Strength (RSS) values. After preprocessing, Universal Kriging (UK) algorithm is adopted to reduce the efforts of establishing a fingerprinting database by Spatial Interpolation. A machine learning algorithm named K -Nearest Neighbour (KNN) is used to calculate user equipment’s position. Real experiments are setup with 5G signals over the air. Two indoor scenarios are considered depending whether the base station is located in the same room with user equipment or not. In test room A, the proposed KF and UK algorithms achieve 53% positioning accuracy improvement. In test room B, 43% performance improvement is obtained by the proposed algorithm. 1.44-meter positioning error is observed as the best case for 80% test samples.
