  1. 1. Applying OSTBC in Cooperative Cognitive Radio Networks

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Hamid Shahzad; Jaishankar Botchu; [2010]
    Nyckelord :Cognitive Radio; Cooperative Communication; OSTBC; Rayleigh Fading; Alamouti STBC; AF Relay; MRC; Energy Detector ;

    Sammanfattning : In this report, we introduce cooperative spectrum sensing using orthogonal space time block coding (OSTBC) in order to achieve cooperative diversity in the cognitive radios (CRs) network. Transmit diversity or gain is achieved by introducing more than one antenna on the transmitter and receiver side, but in small electronic mobile devices it looks impractical. LÄS MER

    Nyckelord :Keywords: Ad hoc network; MANET; MPLS;

    Sammanfattning : Mobile Ad Hoc Network (MANET) is special kind of wireless network which does not have any fixed structure. They are paired for specific purpose within some concise time period. LÄS MER

  3. 3. Internet Protocol based Mobile Radio Access Network Architecture for Remote Service Areas

    Master-uppsats, KTH/Kommunikationssystem, CoS; KTH/Kommunikationssystem, CoS

    Författare :Hamid Shahzad; Nishant Jain; [2007]
    Nyckelord :IP backbones; radio access networks; call routing; All-IP networks;

    Sammanfattning : When it comes to their Radio Access Network (RAN) infrastructure, no two Mobile Operators, serving remote service areas, are alike. Despite situations and technologies being diverse, a well designed optimized RAN solution must adapt itself to the existing networking technologies, both with regard to legacy core networks and modern telecommunication networks in order to produce the best network which is possible subject to many constraints.
