This paper proposes a cooperative wireless relay network consisting of a one-source-one-destination node pair and N relay nodes in three wireless communication environments, i.e., jamming, node geometry, and channel uncertainty. The main objective of this paper is to analytically derive the optimal cooperative amplify-and-forward (AF) wireless relay matrix under three conditions with the relay power...
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...
This paper presents node geometry and broadband jamming in noncooperative wireless relay networks under the received power constraint. Diagonal relay amplifying matrices based on minimum mean square error (MMSE) criteria corresponding to node geometry and broadband jamming in wireless networks under the received power constraint are derived. All relay nodes are assumed not to communicate with their...
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...
The main contribution of this paper is the derivation of an optimal diagonal amplifying relay matrix. This matrix is for a non cooperative distributed wireless relay network in a jamming environment. Minimum mean square error (MMSE) criterion was used in this study. Jamming location was also studied in this paper. Results show that diversity of a system can be degraded or even get lost depending on...
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...
