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...

Power-controlled feedback and training for two-way MIMO channels
Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...

Wideband fading channel capacity with training and partial feedback
We consider the capacity of a wideband fading channel with partial feedback, subject to an average power constraint. A doubly block Rayleigh fading model is assumed with finite co...

Stars of vibrating strings: Switching boundary feedback stabilization
We consider a star-shaped network consisting of a single node with N 3 connected arcs. The dynamics on each arc is governed by the wave equation. The arcs are coupled at the node ...

Functional Overlap between Regions Involved in Speech Perception and in Monitoring One's Own Voice during Speech Production
The fluency and the reliability of speech production suggest a mechanism that links motor commands and sensory feedback. Here, we examined the neural organization supporting such ...
