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. ...
Results show that one relay node provides~23 dB performance enhancement at BER, which mitigates the effect of the nondesirable non-line-of-sight (NLOS) links in WBSNs. ...
Recently, cooperative diversity has been proposed as a promising candidate for wireless communication systems. ...
