  3. 2. A Joint Subcarrier/Power allocation Scheme for OFDMA-based Cellular Networks

    Master-uppsats, Kommunikations- och transportsystem; Tekniska högskolan

    Författare :Aamir Abdul Aziz Hasan Ali; Muhammad Adil Shahzad; [2012]
    Nyckelord :;

    Sammanfattning : The assignment of this master thesis consists of initiating power, subcarrier allocation in a dynamic FFR based scheme designed for multi-cell OFDMA networks and to enhance the throughput of all center users in bandwidth hungry borrower cells (overloaded cells) which was previously degraded by original FFR3 scheme as a result of partitioning of system bandwidth into center and edge bands respectively. The method uses band borrowing to compensate center user’s throughput loss in a semi and fully overloaded system. LÄS MER
