— Multiuser diversity is a phenomenon caused by channel variations among different users in a wireless network. Cooperative relaying provides another form of diversity due to the...
Using relays in wireless networks can potentially lead to significant capacity increases. However, within an asynchronous multi-user communication setting, relaying might cause mor...
— We consider a wireless multiuser network where a number of source/destination pairs communicate concurrently over the same physical channel. A set of amplify-and-forward relay ...
Abstract— A novel cluster-based coherent multi-user (MU) relaying system is proposed, where a number of source/destination pairs communicate concurrently over the same physical c...
Abstract—This paper investigates Orthogonal FrequencyDivision Multiple-Access (OFDMA) resource-allocation schemes for two-hop relays in a home Powerline Communication (PLC) netwo...
