Impact of CSI on Distributed Space-Time Coding in Wireless Relay Networks
We consider a two-hop wireless network where a transmitter communicates with a receiver via M relays with an amplify-and-forward (AF) protocol. Recent works have shown that sophis...

On channel estimation and optimal training design for amplify and forward relay networks
In this paper, we provide a complete study on the training based channel estimation issues for relay networks that employ the amplify-and-forward (AF) transmission scheme. We first...

What is the space for?: the role of space in authoring hypertext representations
This paper describes our approach of using spatial hypertext as a means separated from an end representation for hypertext authoring. By taking advantage of the power of rich inte...

Distributed Double-Differential Orthogonal Space-Time Coding for Cooperative Networks
— In this paper, distributed double-differential coding is proposed to avoid the problem of carrier offsets in amplify and forward protocol based cooperative network with two rel...
