AMPLIFY and FORWARD COOPERATIVE DIVERSITY for SV MODEL BASED STANDARD UWB SYSTEM
نویسندگان
چکیده
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 cooperation amongst UWB devices. BER performance analysis is provided for the cooperative UWB system with Amplify-and-Forward (AAF) cooperative protocol using different combining method. Further this work also analyses the performance of this protocol subject to positioning of relay between transmitter and receiver. The result indicates that AAF provides better performance over single link transmission. Keywords— AAF, SV Model, UWB, SNR, BER, ERC, FRC, SNRC, ESNRC

Amplify and Forward Cooperative Diversity for Modified SV Model Based UWB Communication System
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 use...
متن کاملDecode and Forward Cooperative Diversity for Modified SV Model Based UWB Communication System
Cooperative wireless networks have emerged as a major technology for future communication systems because cooperation in ad-hoc networks can save limited network resources. Cooperative techniques are the means to adopt the diversity, which is inherent in a wireless medium. While ultra-wideband (UWB) offers high information rates for wireless communication and sensor networks, the EIRP limits on...

This paper studies optimal power allocation to minimize symbol error rate (SER) of amplify-and-forward cooperative diversity networks. First, we analytically solve optimal power allocation problem to minimize SER for three different scenarios, namely, multi-branch single-relay, single-branch multi-relay and multi-branch multi-relay cooperative diversity networks, all subject to a given total re...

This paper proposes a novel green cooperative diversity technique based on suboptimal template-based ultra-wideband (UWB) wireless body sensor networks (WBSNs) using amplify-and-forward (AF) relays. In addition, it analyzes the bit-error-rate (BER) performance of the proposed nodes. The analysis is based on the moment-generating function (MGF) of the total signal-to-noise ratio (SNR) at the des...
