Design of joint network-channel coding based on Turbo code and its performance analysis

open access: yesGong-kuang zidonghua, 2015
According to idea of joint network-channel coding, a scheme of joint network-channel coding based on Turbo code applied to multiple access relay channel was proposed, and implementation of relay node encoding and base station decoding was introduced in ...

Degrees of Freedom for the MIMO Multi-way Relay Channel [PDF]

open access: yes, 2013
This paper investigates the degrees of freedom (DoF) of the L-cluster, K-user MIMO multi-way relay channel, where users in each cluster wish to exchange messages within the cluster, and they can only communicate through the relay. A novel DoF upper bound

Myopic coding in multiple relay channels [PDF]

open access: yesProceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
In this paper, we investigate achievable rates for data transmission from sources to sinks through multiple relay networks. We consider myopic coding, a constrained communication strategy in which each node has only a local view of the network, meaning that nodes can only transmit to and decode from neighboring nodes.

Design Criteria for Hierarchical Exclusive Code with Parameter-Invariant Decision Regions for Wireless 2-Way Relay Channel

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
The unavoidable parametrization of the wireless link represents a major problem of the network-coded modulation synthesis in a 2-way relay channel. Composite (hierarchical) codeword received at the relay is generally parametrized by the channel gain ...

Communicating over Filter-and-Forward Relay Networks with Channel Output Feedback [PDF]

open access: yes, 2015
Relay networks aid in increasing the rate of communication from source to destination. However, the capacity of even a three-terminal relay channel is an open problem.

Zero-Error Relaying for Primitive Relay Channels

open access: yesIEEE Transactions on Information Theory, 2017
In a primitive relay channel, a new one-shot relaying scheme termed color-and-forward is proposed that guarantees a probability of error equal to zero. This relaying scheme constructs a relaying compression graph of relay outputs based on the joint conditional distribution of the relay and destination outputs, and forwards a minimum coloring of this ...

Secure 5G Wireless Communications: A Joint Relay Selection and Wireless Power Transfer Approach

open access: yesIEEE Access, 2016
In this paper, we investigate the secrecy performance of an energy harvesting relay system, where a legitimate source communicates with a legitimate destination via the assistance of multiple trusted relays.

Network Code Design for Orthogonal Two-hop Network with Broadcasting Relay: A Joint Source-Channel-Network Coding Approach [PDF]

open access: yes, 2010
This paper addresses network code design for robust transmission of sources over an orthogonal two-hop wireless network with a broadcasting relay. The network consists of multiple sources and destinations in which each destination, benefiting the relay ...

Compound relay channel with informed relay and destination [PDF]

open access: yes2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009
A two-state compound relay channel is considered where the relay and the destination are informed about the channel state while the source is not. Achievable rates and upper bounds are derived for discrete memoryless and Gaussian models, and specialized to a scenario with orthogonal components.
