A Novel Based on Eigenvector Combine Transmission Diversity Scheme for Ultra-wideband Communication System
一种新的基于特征向量合并的超宽带系统分集方案

Ultra-WideBand (UWB) signal faced badly multi-path fading in indoor environment, RAKE receiver usually is adopted to gather multi-path energy and improve performance. A new diversity scheme is proposed in this paper, which implemented pretreatment in transmitter and RAKE combine in receiver respectively, and then a based on channel matrix eigen-value SVD algorithm is presented to estimated optimal parameter of delay time and combine weight. Both theoretic analysis and simulation show, the algorithm always gains maximized output SNR than conventional RAKE receiver.
