Superposition network coded cooperation for wireless networks
Transactions on Emerging Telecommunications Technologies, 2016AbstractCooperative diversity is an innovative approach to improve the reliability of communication. Although this technique is considered in the next‐generation mobile communication standards, it has its own challenges in practice. For example, in simultaneous transmission‐based cooperative protocols, perfect synchronisation of nodes is very hard to ...

Wireless Network Coding with Cooperative Diversity
Wireless Personal Communications, 2010In this paper we integrate the ideas of network coding and relays into an existing practical network architecture used in a wireless network scenario. Specifically, we use the COPE architecture to test our ideas. Since previous works have focused on the communication aspect at the physical layer level, we attempt to take it one step further by ...

Network Coded Cooperative BICM-OFDM
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011In this paper, we study a cooperative diversity scheme for wireless systems employing network coding and the combination of bit-interleaved coded modulation (BICM) and orthogonal frequency division multiplexing (OFDM). The considered system comprises multiple sources, one relay, and one destination.

Adaptive Cooperative Coding in Wireless Networks
VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008The cooperative transmission is an efficient way in the wireless network which benefits from the spacial diversity. In this paper, we introduce and analyze a novel three-node relay protocol with high transmit efficiency, termed as the Adaptive Cooperative Coding (ACC).

A network coding approach to cooperative diversity
IEEE Transactions on Information Theory, 2007This paper proposes a network coding approach to cooperative diversity featuring the algebraic superposition of channel codes over a finite field. The scenario under consideration is one in which two ldquopartnersrdquo - node A and node B - cooperate in transmitting information to a single destination; each partner transmits both locally generated ...

Adaptive Coded Cooperation in Wireless Networks
2008 International Wireless Communications and Mobile Computing Conference, 2008User cooperation enables single antenna terminals to benefit from spatial diversity by partnering with other users to create a virtual transmit antenna array. A promising form of cooperation is called coded cooperation which integrates cooperation with channel coding, showing great performance gains.

User Cooperation Through Network Coding
2007 IEEE International Conference on Communications, 2007Most user cooperation protocols work in a timesharing manner, where each user transmits its own message and relays for the other at different segments of a time slot. We develop a new scheme to send these messages simultaneously using network coding.

Cooperation-Based Network Coding in Cognitive Radio Networks
2014 IEEE 80th Vehicular Technology Conference (VTC2014-Fall), 2014We consider a scenario consisting of a primary and asecondary system, each represented by a pair of a transmitter anda receiver.

Network Coding Based on Product Codes in Cooperative Relaying
2010 IEEE Wireless Communication and Networking Conference, 2010Employing network coding at the relay in cooperative relay system can improve the system throughput. However, XOR based network coding does not provide a strong error correction capability that can be used at the base station (receiver) in decoding the information of the cooperating users.
