Amplify and Forward Cooperative Diversity for Modified SV Model Based UWB Communication System
نویسنده
چکیده
Cooperative diversity has emerged as a major technique of providing gains from spatial diversity to devices/terminals. While ultra-wideband (UWB) offers high information rates for wireless communication and sensor networks, the EIRP limits on UWB devices severely affects its coverage radius. In this paper, a low complexity cooperative diversity scheme for UWB channel is proposed. The scheme uses Amplify-andForward (AAF) cooperative protocol to ascertain the BER performance. Different combining methods are used and their performances for UWB system are analyzed. Performance analysis based on positioning of the relay has been carried out. The result indicates that AAF provides satisfactory performance over direct link transmission.

Data rates and quality of service are limited by the fact that, for the duration of any given connection, they experience severe variation in signal strength. As reported any UWB system faces major challenges in achieving wide coverage without affecting the system performance. In this paper, a cooperative scheme in UWB is proposed so as to enhance the performance and coverage of UWB by using co...
