In wireless communication systems, adaptive modulation and coding (AMC) is used to improve the downlink (DL) spectral efficiency by exploiting the underlying channel condition. Ho...
Multi-hop relaying will play a central role in next generation wireless systems. In this paper a novel relaying strategy that uses multiple-input multiple-output (MIMO) relays in ...
Cross-Layer design has been the focus of several recent research efforts. Due to the highly variable nature of the links used in wireless communication systems and the resource-po...

Abstract-- Relaying and orthogonal frequency division multiple access (OFDMA) are the accepted technologies for emerging wireless communications standards. The activities in many w...
ATM (asynchronous transfer mode) aims at providing both guaranteed bandwidth to support real-time communications and dynamic bandwidth sharing to accommodate bursty data traffic. ...
