Randomized Isometric Linear-Dispersion Space-Time Block Coding for the DF Relay Channel
This article presents a randomized linear-dispersion space-time block code for decode-andforward synchronous relays. The coding matrices are obtained as a set of columns (or rows)...

Delay-tolerant decode-and-forward based cooperative communication over Ricean channels
In this paper, we propose a TDMA based simple transmission scheme, which overcomes the effect of the delays caused by the poor synchronization of the relaying nodes over Ricean ch...

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...

To Code or Not To Code in Multi-Hop Relay Channels
Multi-hop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-tim...

Multi-Frame Distributed Protocol for Analog Network Coding in Slow-Fading Channels
The wireless network scenario here is based on N users that communicate one with the others through a central relay node by adopting the Analog Network Coding (ANC) paradigm. In th...
