Quantized transmit beamforming with antenna selection in a MIMO channel
For a point-to-point multi-input multi-output (MIMO) wireless channel, we propose a feedback scheme, which consists of transmit-antenna selection algorithm and beamforming quantiz...

Distributed one bit feedback extended orthogonal space time coding based on selection of cyclic rotation for cooperative relay n
In this paper, a novel closed-loop distributed extended orthogonal space time block code (D-EO-STBC) with one-bit feedback based on selection of phase rotation is proposed for two...

Performance of asynchronous two-relay two-hop wireless cooperative networks
In wireless cooperative networks, the asynchronism between the relays can be a source of diversity which is similar in its essence to the multipath diversity of frequency selectiv...

Collaborative Signal Reinforcement in Sensor Networks
Nodes in sensor fields and in autonomous swarms of mobile robots need to communicate; this usually requires individual nodes to either consume a significant amount of energy, ca...
