This paper proposes a two-way amplify-and-forward (AF) wireless relay network consisting of two sources with a single antenna and one relay with multiple antennas. The relay amplifying matrix under a power constraint at the relay is presented. The minimum mean square error (MMSE) criterion with self-interference cancelation is employed using vectorization and singular value decomposition (SVD) methods,...
Communication between mobile relays has recently gained much attention. In this paper, a novel optimal diagonal relay amplifying matrix based on the minimum mean square error (MMSE) criterion is proposed for mobile nodes. It is also designed for noncooperative distributed wireless mobile nodes under both no-jamming and jamming environments. An amplify and forward (AF) strategy is considered. The system...
This paper studied a new approach designed for a distributed wireless network under three adverse communication environment, such as, broadband noise jamming (BNJ), node geometry, and channel uncertainty. It is designed for a cooperative network consisting of one-source, one-destination and N-relay nodes that implement amplify-and-forward (AF) strategy. Deriving optimal relay amplifying matrix is...
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...
