Opportunities, Constraints, and Benefits of Relaying in the Presence of Interference
In this paper the interference channel is extended by additional relay nodes in order to investigate the influence of interference on the design and performance of relaying protoco...

Asymptotic Distortion Performance of Source-Channel Diversity over Multihop and Relay Channels
—A key challenge in the design of real-time wireless multimedia systems is the presence of fading coupled with strict delay constraints. A very effective answer to this problem i...

Partially-coherent distributed space-time codes with differential encoder and decoder
Abstract— Distributed space-time coding is a means of achieving diversity through cooperative communication in a wireless relay network. In this paper, we consider a transmission...

Blind Cooperative Diversity Using Distributed Space-Time Coding in Block Fading Channels
— Mobile users with single antennas can still take advantage of spatial diversity through cooperative space-time encoded transmission. In this paper, we consider a scheme in whic...
