The approximate optimality of simple schedules for half-duplex multi-relay networks

L'union d'ordinateurs toujours plus puissants et d'applications gourmandes en ressources réseau a créé un besoin pour une capacité réseau, ou bande passante, de loin supérieure aux

We investigated the asymptotic iterative performance of block-Markov BE-LDPC and BL-LDPC codes over the binary erasure relay channel.. Working with such a simple channel model

We investigate two scenarios for the channel gains: 1) long-term static channel, where the fading is constant for all the channels over all retransmission (ARQ) rounds, and

However, it is interesting to observe that the benefit - in terms of spectral efficiency - of utilizing a relay (baseline two-hop communication scheme) over the classical

For each of the decoding operations during Phases I and II, the BLER performances at the relay and destination are validated for different values of C (at the relay) and evaluated

As an example, for N -relay Gaussian networks with independent noises, where each node in equipped with multiple antennas and where each antenna can be configured to listen or

The channel state infor- mation (CSI) is assumed to be absent at the node which is transmit- ting. Because of the ARQ protocol, limited feedback is received by the transmitting

In [7], by leveraging properties of the Lov´asz extension of a submodular function and the optimality of basic feasible solutions in linear programs, we proved the conjecture of [5]
