— In this paper, we investigate resource allocation for a multi-user OFDMA cooperative system. Aiming at minimizing the total transmission power under target rate constraints for...
Recently, a cooperative paradigm for single-channel cognitive radio networks has been advocated, where primary users can leverage secondary users to relay their traffic. However, i...
— A novel, practical and low-complexity multi-cell OFDMA downlink channel assignment method using a graphbased approach is proposed in this work. The inter-cell interference (ICI...
