— 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...
- In this paper we propose two adaptive schemes for improving the achievable Bandwidth Efficiency (BE) of cooperative diversity aided wireless networks. These schemes are capable ...
Abstract—Ubiquitous network connectivity and mobile communications have recently attracted remarkable attention. Wireless multihop networks such as Mobile Ad hoc Networks or Wire...
