We consider a system in which two users communicate with a destination with the help of a halfduplex relay. Based on the compute-and-forward scheme, we develop and evaluate the performance of coding strategies that are of network coding spirit. In this framework, instead of decoding the users’ information messages, the destination decodes two integer-valued(More)

In this paper, we consider a system in which multiple users communicate with a destination with the help of multiple half-duplex relays. Based on the compute-and-forward scheme, each relay, instead of decoding the users’ messages, decodes an integer-valued linear combination that relates the transmitted messages. Then, it forwards the linear combination(More)
We consider the two user wireless Multiple Access<lb>Relay Channel (MARC), in which nodes A and B want to<lb>transmit messages to a destination node D with the help of a relay<lb>node R. For the MARC, Wang and Giannakis proposed a Com-<lb>plex Field Network Coding (CFNC) scheme. As an alternative,<lb>we propose a scheme based on Physical layer Network(More)
We consider a system that consists of two sources, a half-duplex relay, and a destination. The sources want to transmit their messages reliably to the destination with the help of the relay. We study and analyze the performance of two transmission schemes in which the relay implements decode-andforward strategy. In the first scheme, we incorporate(More)
We study a system in which two sources communicate with a destination with the help of a half-duplex relay. We consider a decoding strategy, based on the compute-and-forward strategy, in which the destination decodes two integer-valued linear combinations that relate the transmitted codewords. In this strategy, the relay compresses its observation using(More)
We consider a communication system in which two sources communicate with a destination with the help of a common relay. We assume that the relay operates in half-duplex mode; and concentrate on the symmetric-rate case. We study and analyse the performance of a simple strategy in which the relay simply amplifies its output and retransmits it. However, unlike(More)
This paper proposes a full-rate cooperative scheme adapted to the slow fading semi-orthogonal multiple access relay channel (MARC). It is assumed that the sources transmit on orthogonal channels and the relay is half duplex transmitting on the same channels as the one of the sources. The sources employ LDPC to encode their messages before transmitting them,(More)
