We consider a system in which two users communicate with a destination with the help of a half-duplex 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(More)
AIMS To characterize the physiological and metabolic responses of Mesorhizobium ciceri strain ch-191 to salt stress, investigating the changes induced by salinity in protein and lipopolysaccharide profiles, as well as determining the accumulation of amino acids, glutamate and proline. METHODS AND RESULTS Strain ch-191 of M. ciceri was grown with different(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)
Alterations of plant growth, nitrogenase activity and nutrient concentration as a consequence of salt treatments were studied in five chickpea (Cicer arietinum L.) cultivars from Spain and Syria. Plants, in symbiosis with Mesorhizobium ciceri ch-191 strain, were grown under controlled conditions for 32 days and subjected to salinity stress. Parameters of(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 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-and-forward strategy. In the first scheme, we incorporate(More)
