Implications Of The Half-Duplex Constraint On Relay-Aided Cooperation Using Rateless Codes
"... Abstract—The half-duplex constraint, which mandates that a cooperative relay cannot transmit and receive simultaneously, considerably simplifies the demands made on the hardware and signal processing capabilities of a relay. However, the very inability of a relay to transmit and receive simultaneous ..."

DMT of parallel-path and layered networks under the half-duplex constraint
- IEEE Trans. Inf. Theory
"... Abstract—In this paper, we study the diversity-multiplexing-gain tradeoff (DMT) of wireless relay networks under the half-duplex constraint. It is often unclear what penalty if any, is imposed by the half-duplex constraint on the DMT of such networks. We study two classes of networks; the first clas ..."

Coding Strategies for Noise-Free Relay Cascades with Half-Duplex Constraint
, 2008
"... Abstract—Two types of noise-free relay cascades are investigated. Networks where a source communicates with a distant receiver via a cascade of half-duplex constrained relays, and networks where not only the source but also a single relay node intends to transmit information to the same destination. ..."

. We introduce two relay channel models, capturing the half-duplex constraint, and within the framework of these models capacity is determined for the first network type. It turns out that capacity is significantly higher than the rates which are achievable with a straightforward time-sharing approach
On Capacity of Deterministic Wireless Networks under Node Half-duplexity Constraint
"... Abstract — In this paper we study the maximum throughput of a single multicast session in wireless networks under a practical constraint that the nodes are half-duplex, i.e. they cannot transmit and receive at the same time. We adapt “deterministic channel model” proposed recently in [1] for modelin ..."

On achievable rate regions for half-duplex causal cognitive radio channels
- in Proc. IEEE Int’l Symp. on Information Theory (ISIT
, 2010
"... Abstract—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 half-duplex constraint is presented, and a new achievable rate region is derived for this channel. It is proved t ..."

On the achievable diversity-multiplexing tradeoff in half-duplex cooperative channels
- IEEE TRANS. INFORM. THEORY
, 2005
"... We propose novel cooperative transmission protocols for delay-limited coherent fading channels consisting of (half-duplex and single-antenna) partners and one cell site. In our work, we differentiate between the relay, cooperative broadcast (down-link), and cooperative multiple-access (CMA) (up-lin ..."

scenarios is that they do not rely on orthogonal subspaces, allowing for a more efficient use of resources. In fact, using our results one can argue that the suboptimality of previously proposed protocols stems from their use of orthogonal subspaces rather than the half-duplex constraint.
Joint Typicality Analysis for Half-Duplex Cooperative Communication
"... Abstract—We propose a half-duplex cooperative scheme for a discrete memoryless channel (DMC) consisting of two users communicating with one destination. The half-duplex constraint is satisfied by performing the communication over 3 time slots with variable durations in each code block. Each user alt ..."

1Interference Channels with Half-Duplex Source Cooperation
"... The performance gain by allowing half-duplex source cooperation is studied for Gaussian interference channels. The source cooperation is in-band, meaning that each source can listen to the other source’s transmission, but there is no independent (or orthogonal) channel between the sources. The half- ..."

Dynamic QMF for Half-Duplex Relay Networks
"... Abstract—The value of relay nodes to enhance the error performance versus rate trade-off in wireless networks has been studied extensively. However, wireless nodes currently are constrained to only transmit or receive at a given frequency, i.e., half-duplex constraint. The diversity-multiplexing tra ..."

"... We develop and analyze low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks. The underlying techniques exploit space diversity available through cooperating terminals’ relaying signals for one another. We outline several strategies ..."
