Noncooperative distributed MMSE relay schemes under jamming environment and node geometry in wireless relay networks

The main contribution of this paper is the derivation of optimum relay amplifying matrices for noncooperative distributed wireless amplifying-and-forward relay networks. Channels connecting any two nodes are under fading, and either partial-band noise jamming or non-symmetrical node geometry. The minimum mean squared error criterion is used for the optimality. With the derived optimum relay amplifying matrices, the bit error rate is compared through simulation for various situations.
