Dynamic Subcarrier, Bit and Power Allocation in OFDMA-Based Relay Networks Through Efficient Optimization Approach

Free registration required

Executive Summary

The utilization of Relay Stations (RSs) and the employment of Orthogonal Frequency Division Multiple Access (OFDMA) have been extensively renowned as a capable technique for future cellular infrastructure due to the performance enhancement by flexible resource allocation approaches. The downlink of a cell is taken into consideration in an OFDMA based relay network. In the cell, a Base Station (BS) and fixed Relay Stations (RSs) are deployed. Multiple Subscriber Stations (SS) are positioned in the cell. A SS is served either by a direct or a two hop connection. A connection between BS and SS is present in a direct connection. In a two hop connection, a connection exists between BS and RS and between RS and SS.
