This paper considers the problem of applying compressed sensing ideas to relay networks in order to increase the network throughput. We present a new method to perform forwarding which, when the signals transmitted by several sources are jointly sparse, enables to send a vector of dimension higher than the min-cut of the network. First, the jointly sparse source signals are mapped to a signal of lower dimension which can be transmitted over the network. Second, we allow source nodes to send atdoi:10.1109/icc.2011.5962870 dblp:conf/icc/CorroyM11 fatcat:5wty7bux7vb53ahld7m3ajco2i
