The periodic broadcasting of frequently requested data can reduce the workload of uplink channels and improve data access for users in a wireless network. Since mobile devices hav...
In this paper we consider MIMO system with Mt transmitting and Mr receiving antennas, when channel state information (CSI) is known on the transmitter side. The Reyleigh fading cha...
Abstract—This paper investigates Orthogonal FrequencyDivision Multiple-Access (OFDMA) resource-allocation schemes for two-hop relays in a home Powerline Communication (PLC) netwo...
We consider the problem of resource allocation for a Direct Sequence Code Division Multiple Access (DS-CDMA) wireless visual sensor network (VSN). We use the Nash Bargaining Solut...
