  • Hollow-Core Optical Fibers 

    Komanec, M.; Dousek, D.; Suslov, D.; Zvanovec, S. (Společnost pro radioelektronické inženýrství, 2020-09)
    Today hollow-core optical fibers (HCF) are on the verge of surpassing the attenuation benchmark of silica single-mode optical fibers used in optical communication. Compared to solid-core optical fibers, HCFs exhibit ultra-low ...
  • Investigation of Stacked Balanced-Fed Patch Antenna for Millimeter-Wave Application 

    Gharbi, I.; Barrak, R.; Diallo, A.; Ribero, J. M.; Ragad, H.; Menif, M. (Společnost pro radioelektronické inženýrství, 2020-09)
    A stacked patch antenna with balanced feed operating in millimeter-wave band is proposed in this paper. Initially, a single balanced-fed patch antenna is designed in three layers. Simulation results show that the proposed ...
  • Machine Intelligence Technique for Blockage Effects in Next-Generation Heterogeneous Networks 

    Amalorpava Mary Rajee, S.; Merline, A. (Společnost pro radioelektronické inženýrství, 2020-09)
    Millimeter wave (mmWave) links such as 28 GHz and 60 GHz propose high data rates and capacity needed in 5G Heterogeneous network (Hetnet) real-time system. The key factors in network planning of Hetnet are the locations ...
  • A Novel Negative Meander Line Design of Microstrip Antenna for 28 GHz mmWave Wireless Communications 

    Kamal, S.; Mohammed, A. S. B.; Bin Ain, M. F.; Ullah, U.; Hussin, R.; Ahmad, Z. A.; Othman, M.; Ab Rahman, M. F. (Společnost pro radioelektronické inženýrství, 2020-09)
    The increasing applications for nomadic computing have experienced enormous development over the preceding decade. This has eventually caused the lack of bandwidth. Therefore, to accomplish the need of consumers, compact ...
  • A Novel User and Antenna Selection Techniques in Massive MIMO 5G Wireless Communication System 

    Sheikh, T. A.; Bora, J.; Hussain, M. A. (Společnost pro radioelektronické inženýrství, 2020-09)
    In this paper, we have proposed a new paradigm for user scheduling in large-scale multiple-input multiple-output (MIMO) time division duplexing (TDD) system. In this paper, we have selected the users from different groups ...
  • Passive Presence Detection Algorithm for Wi-Fi Sensing 

    Lomayev, A.; da Silva, C. R. C. M.; Maltsev, A.; Cordeiro, C.; Sadri, A. S. (Společnost pro radioelektronické inženýrství, 2020-09)
    In this paper, we derive a signal processing algorithm that enables a Wi-Fi station to passively detect the presence of a potential user in its vicinity. It is assumed that the potential user either doesn’t carry a Wi-Fi ...
  • A Planar Dual-Band UHF RFID Tag for Metallic Items 

    Bouazza, H.; Lazaro, A.; Bouya, M.; Hadjoudja, A. (Společnost pro radioelektronické inženýrství, 2020-09)
    In this paper, a comparison of three tags based on modified patches for UHF RFID in term of size and read range performance is proposed. The antenna structure consists of a patch with an open stub and meander line for feed. ...
  • Robust Student’s T Distribution Based PHD/CPHD Filter for Multiple Targets Tracking Using Variational Bayesian Approach 

    Li, P.; Xu, C.; Wang, W.; Su, S. (Společnost pro radioelektronické inženýrství, 2020-09)
    Measurement-outliers caused by non-linear observation model or random disturbance will lead to the accuracy decline of a target tracking filter. This paper proposes a robust probability hypothesis density (PHD) filter to ...
  • SDR Verification of Hierarchical Decision Aided 2-Source BPSK H-MAC CSE with Feed-Back Gradient Solver for WPNC Networks 

    Hron, P.; Lukac, J.; Sykora, J. (Společnost pro radioelektronické inženýrství, 2020-09)
    This paper considers a channel state estimation (CSE) problem in a parametrized Hierarchical MAC (H-MAC) stage in Wireless Physical Layer Network Coding (WPNC) networks with Hierarchical Decode and Forward (HDF) relay ...
