Dynamic Selective Decode and Forward in wireless relay networks

2015 7th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT), 2015
In this paper, we propose a practical code design for a new relaying protocol, coined Dynamic Selective Decode-and-Forward (D-SDF), in half-duplex slow fading Multiple Access Multiple Relay Channel (MAMRC), defined as follows: (1) Multiple statistically independent sources communicate with a single destination with the help of multiple half-duplex ...

Bilayer LDPC Convolutional Codes for Decode-and-Forward Relaying

IEEE Transactions on Communications, 2013
In this paper we present bilayer LDPC convolutional codes for half-duplex relay channels. Two types of codes, bilayer expurgated LDPC convolutional codes and bilayer lengthened LDPC convolutional codes, are proposed for decode-and-forward (DF) relaying.

Performance Evaluation of Decode-and-Forward Satellite Relaying

IEEE Transactions on Vehicular Technology, 2015
In this paper, we consider decode-and-forward (DF) relaying of the data of a multiple-antenna-based source Earth station, via a single-antenna-based satellite, to a multiple-antenna-based destination Earth station. The source uses beamforming for transmission of the data, and the destination utilizes the maximal ratio combining for demodulating the ...

Orthogonal decode and forward relaying with improved spectral efficiency

IEEE Communications Letters, 2009
Cooperative relay communications can significantly improve the reliability of data transmission over wireless fading channels by implementing spatial diversity in a distributed fashion. Orthogonal decode and forward (ODF) relaying achieves maximum diversity provided by the source-destination and relay destination channels, but suffers from low spectral

Detectors for Cooperative Mesh Networks With Decode-and-Forward Relays

IEEE Transactions on Signal Processing, 2015
We consider mesh networks composed of groups of relaying nodes which operate in decode-and-forward mode. Each node from a group relays information to all the nodes in the next group. We study these networks in two setups, one where the nodes have complete state informationabout the channels through which theyreceivethesignals ...

Energy Efficiency of Decode-and-Forward for Wideband Wireless Multicasting

IEEE Transactions on Information Theory, 2011
In this paper, we study the minimum energy per bit required for communicating a message to all the destination nodes in a wireless network. The physical layer is modeled as an additive white Gaussian noise (AWGN) channel affected by circularly symmetric fading. The fading coefficients are known at neither transmitters nor receivers.
