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...
—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...
— 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...
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...
—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...
