Abstract :
This paper studies channel uncertainty and node geometry influences on a regenerative distributed decode-and-forward (DF) wireless relay network. A network consisting of one-source-one-destination pair and N-multibranch relay nodes without a direct link between the source and the destination is investigated. A new proposed detection scheme employs the maximum ratio combiner (MRC) principle. The new detection scheme is applied at both relay nodes and the destination node, to optimally detect the original transmitted message from the source node. Monte-Carlo simulations were used to evaluate the bit error rate (BER) performance for the regenerative distributed DF wireless relay network using the new proposed MRC scheme.
