  • Analysis of Multipath Mitigation Techniques with Land Mobile Satellite Channel Model 

    Bhuiyan M. Z. H.; Zhang, J.; Lohan, E. S.; Wang, W.; Sand, S. (Společnost pro radioelektronické inženýrství, 2012-12)
    Multipath is undesirable for Global Navigation Satellite System (GNSS) receivers, since the reception of multipath can create a significant distortion to the shape of the correlation function leading to an error in the ...
  • A Centralized Processing Framework for Foliage Penetration Human Tracking in Multistatic Radar 

    Zhang, J.; Jin, T.; He, Y.; Zhou, Z. M. (Společnost pro radioelektronické inženýrství, 2016-04)
    A complete centralized processing framework is proposed for human tracking using multistatic radar in the foliage-penetration environment. The configuration of the multistatic radar system is described. Primary attention ...
  • Direction-of-Arrival Estimation for Arbitrary Array: Combining Spatial Annihilating and Manifold Separation 

    Pan, Y.; Zhang, J.; Qi, Z. (Společnost pro radioelektronické inženýrství, 2019-04)
    In this paper, we address the problem of direction-of-arrival (DOA) estimation with the arbitrary array. The manifold separation technique (MST) is employed to transform the arbitrary array into a virtual array with ...
  • An Efficient Forensic Method for Copy–move Forgery Detection based on DWT-FWHT 

    Yang, B.; Sun, X.; Chen, X.; Zhang, J.; Li, X. (Společnost pro radioelektronické inženýrství, 2013-12)
    As the increased availability of sophisticated image processing software and the widespread use of Internet, digital images are easy to acquire and manipulate. The authenticity of the received images is becoming more and ...
  • Intelligent Ray Launching Algorithm for Indoor Scenarios 

    Lai, Z.; De La Roche, G.; Bessis, N.; Kuonen, P.; Clapworthy, G.; Zhou, D.; Zhang, J. (Společnost pro radioelektronické inženýrství, 2011-06)
    This article describes the indoor IRLA (Intelligent Ray Launching Algorithm), which originates from an efficient outdoor propagation prediction model. Implementation and validation are given in detail. An indoor office ...
  • Matching Theory for Channel Allocation in Cognitive Radio Networks 

    Cao, L.; Yao, F.; Zhao, H.; Zhang, J. (Společnost pro radioelektronické inženýrství, 2016-12)
    For a cognitive radio network (CRN) in which a set of secondary users (SUs) competes for a limited number of channels (spectrum resources) belonging to primary users (PUs), the channel allocation is a challenge and dominates ...
  • Modeling the AgInSbTe Memristor 

    Yu, J.; Li, Y.; Mu, X.; Zhang, J.; Miao, X.; Wang, S. (Společnost pro radioelektronické inženýrství, 2015-09)
    The AgInSbTe memristor shows gradual resistance tuning characteristics, which makes it a potential candidate to emulate biological plastic synapses. The working mechanism of the device is complex, and both intrinsic ...
  • Satellite Communication Synchronization Based on Combining Multi-Differential Correlations in the High Doppler Channel 

    Liu, J.; Wang, S.; Hao, Z.; Zhang, J. (Společnost pro radioelektronické inženýrství, 2021-04)
    In this paper, a pilot-aided synchronization method based on combining multi-differential correlations (MDCS) is proposed to overcome the obstacles in the synchronization of high-speed mobile satellite communication links. ...
  • Watermarking FPGA Bitfile for Intellectual Property Protection 

    Zhang, J.; Lin, Y.; Wu, Q.; Che, W. (Společnost pro radioelektronické inženýrství, 2012-06)
    Intellectual property protection (IPP) of hardware designs is the most important requirement for many Field Programmable Gate Array (FPGA) intellectual property (IP) vendors. Digital watermarking has become an innovative ...
