    Reliable Multi-hop Routing with Cooperative Transmissions in Energy-Constrained Networks
    Download  research.sabanciuniv.edu
    We present a novel approach in characterizing the optimal reliable multi-hop virtual multiple-input single-output (vMISO) routing in ad hoc networks. Under a high node density regi...

    Generalized Window-Based PN Acquisition Scheme in CDMA Spread Spectrum Systems
    Download  wiselab.korea.ac.kr
    In this letter, we propose a generalized version of the window-based pseudonoise (PN) acquisition scheme verifying one or more best hypotheses rather than the best one per search w...

    A Reduced-PAR Opportunistic STBC Scheme for Frequency-Selective Channels in the Presence of Frequency Offset
    Download  www.utdallas.edu
    Opportunistic space-time block codes (STBC) have been investigated for flat-fading channels in the literature. In this paper, we present a novel scheme for integrating them with or...
