An efficient probing mechanism for next generation mobile broadband systems
(2012)Opportunistic scheduling exploits multiuser diversity for improving the performance of wireless systems. However, it requires instantaneous channel state information (CSI) to be available at the transmitter side. Since ... -
Low complexity algorithms for relay selection and power control in interference-limited environments
(2010)We consider an interference-limited wireless network, where multiple source-destination pairs compete for the same pool of relay nodes. In an attempt to maximize the sum rate of the system, we address the joint problem of ... -
Orthogonal Frequency Division Multiplexing for 4G Mobile Communication Systems
(2010)Evolution in mobile communications demands development of ideal mechanisms in order to approach a new generation (4th Generation). Such mechanism is Orthogonal Frequency Division Multiplexing (OFDM), which is a multi-carrier ... -
Reconfiguration between the different congestion avoidance and control algorithms for 4G handsets
(2012)This is a project that involves the investigation of autonomic technology to enable reconfiguration of the Media Access Control (MAC) in future 4G networks. The main aim is to examine how contention and congestion methods ...
