  • REVIEW ON SYNCHRONIZATION ISSUES IN COGNITIVE RADIO
    Uday V Wali*, Sandeep S Bidwai    Download Full Text

    Cognitive Radio (CR) for dynamic spectrum access enables opportunistic use of the radio-frequency (RF) spectrum, allowing unlicensed users to utilize licensed bands under the condition that they interfere as little as possible with the licensees. In this paper a survey on performance of cognitive radio is made. The performance parameters includes synchronization issues like frequency & timing erro...

  • GROUNDED FREQUENCY SELECTIVE SURFACE ARRAY CHARACTERIZATION FOR 180° PHASE DELAY REALIZATION IN W-BAND
    S. Islam, J. Stiens, and R. Vounckx    Download Full Text

    We describe the design, fabrication and bench-study of mm-wave quasi optical phase shifter by using grounded Frequency Selective Surface (FSS) on Roger 4003C substrate. This paper provides the basis for an understanding of FSS-based free space phase delay realization by using a FSS array composed of two sub-arrays of different slot lengths. The simulation and measurement results at W-band demonstr...

  • MITIGATION OF RAILWAY VIBRATIONS BY USING BARRIERS
    M. Buonsanti, F. Cirianni, G. Leonardi and F. Scopelliti    Download Full Text

    The problem of the ground-borne vibrations caused by high speed trains has received considerable attention in recent years, due to the effects it can have on buildings, in terms of physical damage, the population, in terms of disconfort. The problem has become more significant with the increase of speed and weight of trains, which results with heavier loads on the tracks. In order to predict the ...
