Optimal channel assignment and power allocation for dual-hop multi-channel multi-user relaying
Abstract—We consider the problem of jointly optimizing channel pairing, channel-user assignment, and power allocation in a single-relay multiple-access system. The optimization o...

Power Allocation in Team Jamming Games in Wireless Ad Hoc Networks
In this work, we study the problem of power allocation in teams. Each team consists of two agents who try to split their available power between the tasks of communication and jam...

Training design in single relay AF cooperative systems with correlated channels
In this paper, training design is studied for a single relay amplify-and-forward cooperative network. The taps of the frequency selective channels are assumed to be correlated and...

Max-min fair rate control based on a saddle-point characterization of some perron roots
We consider a power-controlled wireless network with an established network topology in which the communication links (transmitter-receiver pairs) are subject to general constrain...

Performance analysis and power allocation for M-QAM cooperative diversity systems
An adaptive regenerate and forward cooperative diversity (CD) system using quadrature amplitude modulation (QAM) for a two-user cooperation is proposed. The proposed system can ach...
