MIMO DF Relay Beamforming for Secrecy with Artificial Noise, Imperfect CSI, and Finite-Alphabet
In this paper, we consider decode-and-forward (DF) relay beamforming with imperfect channel state information (CSI), cooperative artificial noise (AN) injection, and finitealphabet input in the presence of an user and J non-colluding eavesdroppers. The communication between the source and the user is aided by a multiple-input-multiple-output (MIMO) DF relay. We use the fact that a wiretap code ...
متن کاملSNR Maximization at CSI Aware AF Relay
This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...
متن کاملSecure Communication for Two-Way Relay Networks with Imperfect CSI
This paper considers a two-way relay network, where two source nodes exchange messages through several relays in the presence of an eavesdropper, and the channel state information (CSI) of the eavesdropper is imperfectly known. The amplify-and-forward relay protocol is used and the relay beamforming weights are designed. The model is built up to minimize the total relay transmit power while gua...

متن کاملOn the MIMO Capacity with Imperfect CSI
Multiple-input multiple-output (MIMO) antenna systems provide high capacity gain over a single-antenna system. This gain is maximised when channel state information (CSI) is available at the transmitter. In practice, however, only partial information could be obtained. In this paper, we shall present a study of the MIMO system capacity in the case of imperfect CSI. It is found that in the case ...
