An Ultra-Wideband Cooperative Communication Method Based on Transmitted Cooperative Reference

摘要

In order to decrease the power waste of relay node, the paper presents a novel ultra-wideband cooperative communication method that uses two relay nodes to transmit reference impulses and data impulses separately. A transmitted cooperative-reference UWB cooperative communication model is developed in this paper. Based on the model and sampling expansion approach, a closed-form SER expression was deduced for delay-hopped transmitted-reference UWB systems which use cooperation strategy of decode and forward relaying and equal-gain combining. Simulation results show that the transmitted cooperative-reference method can obtain multi-order diversity gains.
