Abstract— This paper discusses channel estimation in a cooperative orthogonal frequency-division multiplexing (OFDM) network in the presence of frequency offsets. Both the amplif...
A random access protocol named ALLIANCES was recently proposed, that achieves high throughput by resolving collisions in wireless networks. ALLIANCES exploits diversity provided b...
—By providing coding ability at intermediate nodes, network coding has been shown to improve throughput in wireless broadcast/multicast networks. Considering a scenario where wir...
Abstract-- Most user cooperation protocols work in a timesharing manner, where each user transmits its own message and relays for the other at different segments of a time slot. We...
—The provision of very high data rates in a ubiquitous manner throughout the service area is a great challenge for 4G and beyond-4G wireless networks. Towards that end, the deplo...
