  • Array Pattern Synthesis Using a Digital Position Shift Method 

    Han, C.; Wang, L. (Společnost pro radioelektronické inženýrství, 2016-09)
    Considering all possible steering directions for beam scanning, a digital position shift method (DPSM) is presented to minimize the Peak Sidelobe Level (PSL) by searching the best position solution for every sensor and ...
  • Classification and Localization of Mixed Sources Using Uniform Circular Array under Unknown Mutual Coupling 

    Wang, K.; Wang, L.; Xie, J.; Tao, M. (Společnost pro radioelektronické inženýrství, 2019-04)
    In this paper, the authors propose an effective classification and localization algorithm of mixed far-field and near-field sources using a uniform circular array under the unknown mutual coupling. In practice, the assumption ...
  • Improving 3D-Turbo Code's BER Performance with a BICM System over Rayleigh Fading Channel 

    Yao, R.; Zhu, Y.; Xu, J.; Gao, F.; Wang, L. (Společnost pro radioelektronické inženýrství, 2016-12)
    Classical Turbo code suffers from high error floor due to its small Minimum Hamming Distance (MHD). Newly-proposed 3D-Turbo code can effectively increase the MHD and achieve a lower error floor by adding a rate-1 post ...
  • Linear Array Pattern Synthesis Using An Improved Multiobjective Genetic Algorithm 

    Han, C.; Wang, L.; Zhang, Z.; Xie, J.; Xing, Z. (Společnost pro radioelektronické inženýrství, 2017-12)
    In this paper, we propose an improved nondominated sorting genetic algorithm-II with scope constrained (INSGA-II/SC) with three modifications, which are dynamic nondomination strategy, scope-constrained strategy, and front ...
  • The MIMO Antenna Array with Mutual Coupling Reduction and Cross-polarization Suppression by Defected Ground Structures 

    Zhang, Z. L.; Wei, K.; Xie, J.; Li, J. Y.; Wang, L. (Společnost pro radioelektronické inženýrství, 2018-12)
    This paper proposes two types of defected ground structures (DGSs) for achieving the mutual coupling (MC) reduction and the antenna cross-polarization (XP) suppression respectively in a MIMO (multiple input multiple output) ...
  • Novel Compact and High Selectivity Dual-band BPF with Wide Stopband 

    Wang, L.; Guan, B.-R. (Společnost pro radioelektronické inženýrství, 2012-04)
    A novel type of compact and high selectivity dual-band bandpass filter (BPF) incorporating a dual-mode defected ground structure resonator (DDGSR) and a dual-mode open-stub loaded stepped impedance resonator (DOLSIR) is ...
  • Novel Fractal DGSs for Band-gap Filter with Improved Q-factor 

    Gong, Y. Y.; Wang, L.; Wei, K.; Zhang, Z. L. (Společnost pro radioelektronické inženýrství, 2017-12)
    This paper presents a novel fractal defected ground structure (FDGS) for designing high Q-factor band-gap filter. Key parameters of the proposed FDGS are studied. The decreased slot distance causes rapid increase in the ...
  • Space Alignment Based on Regularized Inversion Precoding in Cognitive Transmission 

    Yao, R.; Li, G.; Xu, J.; Wang, L. (Společnost pro radioelektronické inženýrství, 2015-09)
    For a two-tier Multiple-Input Multiple-Output (MIMO) cognitive network with common receiver, the precoding matrix has a compact relationship with the capacity performance in the unlicensed secondary system. To increase the ...
  • Study of Horizontally Polarized Omnidirectional Microstrip Antenna Arrays 

    Wei, K.; Li, J. Y.; Wang, L.; Xu, R. (Společnost pro radioelektronické inženýrství, 2017-04)
    This paper presents two microstrip antenna arrays for horizontally polarized (HP) omnidirectional application, namely rectangular patch antenna array and H-shaped patch antenna array. There are eight patch elements placed ...
