Effects of Node Geometry on Noncooperative Distributed SIMO Wireless Relay Networks

In practice, in any wireless network where 1-source, N-relays and M-destinations exist, each relay node will most likely have different separations with the source and any destination. Therefore, relay node geometry effect in a single-input multiple-output (SIMO) system was studied in this paper. The main contribution of this paper is the derivation of an optimal diagonal amplifying relay matrix under node geometry effect. This matrix is designed for a non cooperative distributed wireless relay network. The effect of node geometry in wireless relay networks was studied. The new derived matrix was evaluated using bit error rate (BER). Also, performance comparisons with/without no node geometry were a focus in our study.
