  4. 3. Uplink Load in CDMA Cellular Radio Systems

    Författare :Erik Geijer Lundin; Fredrik Gunnarsson; Oriol Sallent; Linköpings universitet; []
    Nyckelord :CDMA; Uplink Load; Radio Resource Management; Automatic Control; Cellular Radio; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The uplink of code division multiple access (CDMA) cellular radio systems is often interference limited. The interference originates from many users whose transmission powers are not observable for the system. LÄS MER

  5. 4. Hybrid cellular-broadcasting infrastructure systems : radio resource management issues

    Författare :Aurelian Bria; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis addresses the problem of low-cost multicast delivery of multimedia content in future mobile networks. The trend towards reuse of existing infrastructure for cellular and broadcasting for building new systems is challenged, with respect to the opportunities for low cost service provision and scalable deployment of networks.
