- In this thesis, we propose a new adaptive resource allocation scheme for
a downlink orthogonal frequency division multiple access (OFDMA) relay
network with imperfect channel state information (CSI). In the proposed
scheme, the power, subcarrier, and scheduled data rate are allocated to the
BS, relays, and users to maximize the weighted sum of goodput under
power constraints. Simulation results show that the proposed scheme
achieves higher weighted sum of goodput than a conventional scheme.
