Design considerations in cross layer framework for cognitive UWB

Ultra-wideband (UWB) and cognitive radio (CR) are two exciting technologies that offer new approaches to exploit the existing wireless spectrum opportunistically to overcome the limited available spectrum and the inefficiency in the spectrum usage. In Cognitive Ultra Wideband (C-UWB) system which ut...

description Ultra-wideband (UWB) and cognitive radio (CR) are two exciting technologies that offer new approaches to exploit the existing wireless spectrum opportunistically to overcome the limited available spectrum and the inefficiency in the spectrum usage.
