Quantize-Map-and-Forward (QMF) is a recently proposed strategy that allows to approximately achieve the capacity of arbitrary wireless relay networks. The authors present a structured Quantize-Map-and-Forward (QMF) scheme for cooperative communication over wireless networks that employ LDPC ensembles for the node operations and message-passing algorithms for decoding. They demonstrate through extensive simulation results over the full duplex parallel relay network, that their scheme, with no transmits channel state information, offers a robust performance over fading channels and achieves the full diversity order of their network at moderate SNRs.
