Abstract :
This paper presents the effects of relay-node geometry on bit error rate (BER) performance of an amplifying and forward (AF) relay cooperative distributed wireless network. This paper considers one-source-one-destination pair and N relay nodes. In addition, this paper assumes that all relay nodes share their received signals from the source node and the channel coefficients for cooperation. Then, an optimal relay-amplifying matrix is derived using the minimum mean square error (MMSE) criterion under a total power constraint at the relay nodes. Simulation results are presented using the analytically derived amplifying matrix.
