On Achievable Rate Regions for Half-Duplex Causal Cognitive Radio Channels
Debdeep Chatterjee, Tan F. Wong, Ozgur Oyman
Coding for the causal cognitive radio channel, with the cognitive source subjected to a half-duplex constraint, is studied. A discrete memoryless channel model incorporating the ha…
Reliability Bounds for Delay-Constrained Multi-hop Networks
Ozgur Oyman
We consider a linear multi-hop network composed of multi-state discrete-time memoryless channels over each hop, with orthogonal time-sharing across hops under a half-duplex relayin…
Power-Bandwidth Tradeoff in Multiuser Relay Channels with Opportunistic Scheduling
Ozgur Oyman, Moe Z. Win
The goal of this paper is to understand the key merits of multihop relaying techniques jointly in terms of their energy efficiency and spectral efficiency advantages in the presenc…
Multihop Diversity in Wideband OFDM Systems: The Impact of Spatial Reuse and Frequency Selectivity
Ozgur Oyman, J. Nicholas Laneman
The goal of this paper is to establish which practical routing schemes for wireless networks are most suitable for wideband systems in the power-limited regime, which is, for examp…
Opportunism in Multiuser Relay Channels: Scheduling, Routing and Spectrum Reuse
Ozgur Oyman
In order to understand the key merits of multiuser diversity techniques in relay-assisted cellular multihop networks, this paper analyzes the spectral efficiency of opportunistic (…
Power-Bandwidth Tradeoff in Dense Multi-Antenna Relay Networks
Ozgur Oyman, Arogyaswami J. Paulraj
We consider a dense fading multi-user network with multiple active multi-antenna source-destination pair terminals communicating simultaneously through a large common set of mu…
