Error probability bounds for decode-and-forward relaying with two correlated sources
Paper in proceeding, 2011
We derive bounds on the error probability of optimal and sub- optimal detectors in an uncoded decode-and-forward relay system with two correlated information sources. This setup is relevant to wireless sensor networks where nearby sensors collect spatially correlated data. We show that taking into account the source correlation at the relay and at the destination leads to significant performance gains. Simulation results corroborate the tightness of our analytical bounds.
