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.

Enhanced Adaptive Network Coded Cooperation for Wireless Networks
IEEE Transactions on Vehicular Technology, 2018Adaptive network coded cooperation (ANCC) provides a general coded cooperation framework to map the communication connections of a wireless network into the coding constraint. However, random selection policy is assumed at each node to select its retrieval subset, which cannot avoid illness in code graph at the sink.

A Novel Network-Coding-Based Coded Cooperation Scheme
2009 IEEE Wireless Communications and Networking Conference, 2009Coded Cooperation (CC) is a promising user co-operation scheme. In this paper, we propose a novel networ-kcoding-based coded cooperation scheme. When a user decodes its partner's information correctly in the first frame, it transmits the combination of the partner's parity bits and its own parity bits through network coding in the second frame. This is

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.

Strategies and Tradeoffs for Coded Cooperation in Wireless Networks
2007 5th International Symposium on Modeling and Optimization in Mobile, Ad Hoc and Wireless Networks and Workshops, 2007In a wireless network, fading significantly affects the performance, and diversity techniques are used to overcome this issue. Cooperation among nodes provides spatial diversity by means of packet relaying. In coded cooperation, diversity is further enhanced since cooperating nodes transmit different parts of a coded packet on different channels.
