DFG-Noncoherent Communication


The aim of this project is the analysis of the performance limits of non-coherent communication in wireless networks of practical relevance and the investigation of appropriate transmission schemes for these networks. Non-coherent communication addresses the setup where neither transmit nor receive channel knowledge is available at the network nodes. The networks of interest include networks with relays and intereference networks. Preliminary results show that, under certain assumptions, non-coherent communication can attain a significant fraction of the performance of coherent communication in the same setup. Therefore, the investigation of appropriate schemes for non-coherent communication is of practical relevance.  In addition, we expect that the work on non-coherent communication will lead to a better understanding of the performance limits of wireless networks in general.
