Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In this paper, we study the subcarrier allocation problem consider both with subcarrier allocation dynamic frequency reuse in the OFDMA-based relay networks. Firstly, we allocate the subcarriers to the relay stations and direct link users in the first hop. Then, we reuse the subcarriers that allocated to the relay stations in the second hop. Thirdly, we allocate the subcarriers to the relay link users in the decentralized scheme. We finally analyse the performance of our proposed resource allocation scheme, system throughput, the interference of the reused subcarriers, the computational complexity of the scheme. The numerical results show that our proposed resource allocation scheme can significantly improving the system throughput, reducing the computational complexity compared with a normal resource allocation scheme that do not consider with the frequency reuse.
