- W21533162 abstract "In this paper a coded OFDMA downlink concept for 4G in a multi-cell environment is analyzed. A radio resource management can be applied for the downlink transmission scheme and this can improve the performance for low system loads. The paper also examines the use of a time/frequency hopping component. Further investigations are done by introducing a propagation model taking into account path loss and shadowing. Additionally, a Gaussian approximation (GA) for the interfering signals is investigated to reduce the complexity of the multi-cell scenario. Simulation results are given to determine the effectiveness of the proposed radio resource management and time/frequency hopping. Simulations show that the GA is an appropriate assumption for the interfering signals." @default.
