—Recently, spectrum-agile (SA) networks have been recognized as a viable solution to the spectrum-scarcity problem in wireless communications. In SA networks, secondary (unlicens...
Wireless amplify-and-forward relay networks in which the source communicates with the relays and destination in the first phase and the relays forward signals to the destination in...
A cross-layer scheme, namely ALOHA With Collision Resolution (ALOHA-CR), is proposed for high throughput wireless communications in a cellular scenario. Transmission occurs in a t...
