Resource allocation algorithms for multiuser cooperative OFDMA systems with subchannel permutation
— 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...

Resource allocation for cooperative relaying
—The delay-limited capacity of the half-duplex relay channel is analyzed for several cooperative protocols under a long-term average total transmit power constraint. It is assume...

Limited feedback schemes for downlink OFDMA based on sub-channel groups
Abstract--In a downlink Orthogonal Frequency Division Multiple Access (OFDMA) system, optimally allocating sub-channels across mobile users can require excessive feedback of channe...

Power allocation in orthogonal wireless relay networks with partial channel state information
Wireless amplify-and-forward relay networks in which the source communicates with the relays and destination in the first phase and the relays forward signals to the destination in...

Resource Allocation for Wireless Fading Relay Channels: Max-Min Solution
—Resource allocation is investigated for fading relay channels under separate power constraints at the source and relay nodes. As a basic information-theoretic model for fading r...
