Combining Decoded-and-Forwarded Signals in Gaussian Cooperative Channels [PDF]
2006 IEEE International Symposium on Signal Processing and Information Technology, 2006 The goal of this paper is to investigate different ways of combining signals that have been decoded- nd-forwarded by a bunch of relays. We more deeply look at the case where the relays are in bad reception conditions and the cooperation powers are sufficiently high.

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
