The use of multiple antennas at base stations is a key component in the design of cellular
communication systems that can meet high-capacity demands in the downlink. Under ideal …

<? Pub Dtl=""?> The performance of multiuser systems is both difficult to measure fairly and
to optimize. Most resource allocation problems are nonconvex and NP-hard, even under …

We consider decentralized multiantenna cognitive radio networks where the secondary
(cognitive) users are granted simultaneous spectrum access along with the license-holding …

Low Density Signature-Orthogonal Frequency Division Multiplexing (LDS-OFDM) has been
introduced recently as an efficient multiple access technique. In this paper, we focus on the …

In this paper, we address the problem of how to make the wireless service provider (WSP)
earn profits in a wireless video broadcast network with consideration of advertisement …

This study addresses the problem of profit maximization between wireless service providers
(WSPs) and content providers (CPs) in wireless broadcasting systems, while simultaneously …

In this paper, we address the problem of how to make the wireless service provider have
better profits with consideration of user experience provision in wireless video broadcasting …

We consider transmit rate allocation and the associated cooperative decoding strategies in
uplink multi-cell networks where base stations (BSs) are connected by capacity-limited …

A Gaussian multiple access wire-tap channel with confidential messages is studied, where
multiple users attempt to transmit private messages to a legitimate receiver in the presence …
