We investigate the problem of scheduling in OFDMbased multihop relay networks with special emphasis on IEEE 802.16j based WiMAX networks. In such networks, scheduling is the probl...
—Cooperative communications exploit the spatial diversity inherent in multiuser system by allowing cooperation among users having a wide range of channel qualities. How to search...
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 ...
