Blind channel estimation for MPSK-based amplify-and-forward two-way relaying
We consider the problem of channel estimation for amplify-andforward (AF) two-way relay networks (TWRNs). The majority of works on this problem develop pilot-based algorithms that...

HARQ Aided Systematic LT Coding for Amplify-Forward and Decode-Forward Cooperation
—Systematic Luby Transform (SLT) codes constitute rateless codes, which are capable of adaptively adjusting their code rate depending on the channel quality without explicit chan...

On the Performance of Distributed Space-Time Block Coding Over Nonidentical Ricean Channels and the Optimum Power Allocation
— Distributed space-time coding (STC) gives rise to nonidentical channels between different transmit and receive antennas, which are not co-located. Therefore, the performance an...

Cooperative Fading Regions for Decode and Forward Relaying
Abstract--Cooperative transmission protocols over fading channels are based on a number of relaying nodes to form virtual multiantenna transmissions. Diversity provided by these te...

Application of Phase Shift in Coherent Multi-Relay MIMO Communications
—In this paper we propose a new low feedback and low complexity scheme that adjusts the phases at the relays, thus allowing for the coherent combining of signals from multiple re...
