On the energy-delay trade-off of a two-way relay network
—We consider a three node network in which a pair of nodes with stochastic arrivals communicate with each other with the help of an intermediate relay. The bi-directional nature ...

Using Limited Feedback in Power Allocation Design for a Two-Hop Relay OFDM System
In this paper, we study power allocation (PA) in a single-relay OFDM system with limited feedback. We propose a PA scheme that uses a codebook of quantized PA vectors designed offl...

Performance analysis and power allocation for M-QAM cooperative diversity systems
An adaptive regenerate and forward cooperative diversity (CD) system using quadrature amplitude modulation (QAM) for a two-user cooperation is proposed. The proposed system can ach...

Combining adaptive smoothing and decision-directed channel estimation schemes for OFDM WLAN systems
In this paper, a new channel estimation method for OFDM WLAN systems is proposed. This proposal mainly consists of smoothing filtering and decision-directed tracking loop schemes,...

Joint MMSE Transceiver Design for Closed-Loop Non-Regenerative MIMO Relaying Systems
— In this paper, as a extended structure of the existing relay-destination joint minimum mean square error (MMSE) design, we propose a new source-relay-destination joint MMSE des...
