Error bounds for decode-and-forward relaying
2010 European Wireless Conference (EW), 2010We analyze and compare the maximum-likelihood (ML) decoder and the maximum a-posteriori (MAP) decoder for coding over a decode-and-forward relay network with orthogonal channels. Using a specific model for the errors introduced by the relay, we derive an optimal MAP decoder that operates on a super-trellis and estimates jointly the transmitted codeword

Soft Decode and Forward Improves Cooperative Communications
1st IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing, 2005., 2006Mobile receivers can benefit from an increased spatial diversity through cooperation. Two relaying techniques are typically used: either amplify and forward (AF) or decode and forward (DF). This contribution presents a new technique, which combines the main advantages of both AF and DF.

Performance Analysis of Decode-and-Forward based Hybrid RF/FSO-VLC system
International Workshop on Ant Colony Optimization and Swarm Intelligence, 2019This paper presents performance analysis of decode-and-forward (DF) based asymmetric relaying system, where an outdoor hybrid radio frequency (RF)/free space optical communication (FSO) subsystem is connected with an indoor visible light communication ...

Combining forward and backward search in decoding
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013We introduce a speed-up for weighted finite state transducer (WFST) based decoders, which is based on the idea that one decoding pass using a wider beam can be replaced by two decoding passes with smaller beams, decoding forward and backward in time. We apply this in a decoder that works with a variable beam width, which is widened in areas where the ...

Bounding of MAP decode and forward relaying
2010 IEEE International Symposium on Information Theory, 2010We formulate the maximum a posteriori (MAP) rule for the decode-and-forward transmission strategy operating with a noisy relay. From the MAP rule we derive an analytical bound on the error probability, taking into account decoding errors at the relay.

Decode‐and‐forward with full‐duplex relaying
International Journal of Communication Systems, 2011SUMMARYThis paper addresses the full‐duplex relaying. Some expressions for outage and average capacity of a two‐hop cooperative system with a full‐duplex relay are derived under an independent but not identically distributed Rayleigh fading environment. Using these expressions, we provide the performance analysis without Monte Carlo simulations.

BER Performance of Cooperative MIMO Systems with Half-Duplex Decode and Forward Relaying
International Journal of Electrical and Electronic Engineering & Telecommunications, 2019The joint combination of Multiple-Input Multiple-Output (MIMO) technology and relay, known as cooperative MIMO systems, can extremely boost the spectral efficiency of wireless systems.

Dynamic Decode and Forward with Network Coding
2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012This paper is divided into two parts. In the first part, we analyze outage probability of dynamic decode and forward (DDF) with network coding (NC) and compare outage probability with using NC and without using NC. In the second part, we use MATLAB programming language to simulate our system model.

A Software Defined Radio Platform for Decode and Forward Relay Nodes Implementation
IEEE Conference on Standards for Communications and Networking, 2019Relay Nodes (RNs) are being currently studied as a solution for mobile communications in scenarios where the propagation conditions are challenging. This could include high-mobility scenarios, low coverage areas or outdoor to indoor situations.
