A layered detect-compress-and-forward coding scheme for the relay channel

2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017
We develop a practical layered detect-compress-and-forward (LDCF) coding framework for a three-node relay network. Assuming all transmissions to be mapped to Quadrature Amplitude Modulation (QAM) constellations, the LDCF framework at the relay utilizes maximum-likelihood detection, followed by a multi-level convolutional coding structure to achieve ...

Compress-and-Forward Rates for the Gaussian Relay with ISI and Colored Noise

2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
The achievable rate of a relay channel with inter- symbol interference and additive colored Gaussian noise is examined under an input power constraint and the compress-and-forward (CF) strategy at the relay. Using classical techniques, it is shown that the circular degraded relay channels is equivalent to that of the linear one in the limit of infinite

Compress-and-Forward Relaying: Prototyping and Experimental Evaluation Using SDRs

2016 IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016
This paper presents a prototype implementation and experimental performance evaluation of compress- and-forward (CF) relaying using software-defined radios. Under QPSK transmissions from all nodes, the relay demodulates the received signal before applying distributed joint source-channel coding (DJSCC) implemented with the help of an off-the- shelf ...

Compress-and-forward strategy for the relay channel with causal state information

2009 IEEE Information Theory Workshop, 2009
In this paper, we consider a discrete memoryless state-dependent relay channel with non-causal Channel State Information (CSI). We investigate three different cases in which perfect channel states can be known non-causally: i) only to the source, ii) only to the relay or iii) both to the source and to the relay node.

Virtual-MIMO systems with compress-and-forward cooperation

2012
Multiple-input multiple-output (MIMO) systems have recently emerged as one of the most significant wireless techniques, as they can greatly improve the channel capacity and link reliability of wireless communications. These benefits have encouraged extensive research on a virtual MIMO system where the transmitter has multiple antennas and each of the ...
