Abstract

In this paper, we focus on the frequency reuse algorithms for the downlink of fixed two-hop Orthogonal Frequency Division Multiple Access (OFDMA) cellular relaying networks which operate in decode-and-forward and half-duplex mode. An Orthogonal Resource Allocation Algorithm (ORAA) has been proposed in [1]. After analyzing the co-channel interference and SINR of the ORAA, we propose a modified ORAA to improve the spectrum efficiency. Based on this scheme, co-channel interference and SINR are analyzed compared to the ORAA. In the theory analysis, a key design parameter is found and its optimal value is selected through the simulations. Intensive system-level simulation demonstrated the performance of the modified ORAA is superior to the ORAA remarkably.
