Adaptive Compress-and-Forward Relaying in Fading Environments with or without Wyner-Ziv Coding
Abstract--Compress-and-Forward is a protocol for transmission over relay networks in which the relay forwards a compressed version of the signal it observes. The compression method...

Adaptive Bitrate and Resource Allocation for Relay-Assisted ARQ Transmissions
Automatic repeat request (ARQ) protocols deal with the situations where the selected data rate is not supported by the current channel realization. The inappropriate selection is m...

Selective Relaying in Cooperative OFDM Systems: Two-Hop Random Network
— In this paper, we investigate two selective relaying schemes in cooperative OFDM systems. Selective OFDMA relaying, where the relay selection is performed in a per-subcarrier m...
