| 摘 要： | 针对频率选择性衰弱信道下协作通信系统信道估计复杂的问题,提出了一种模拟合并放大转发超宽带(UWB)协作通信方案.该方案在源节点处对发送符号进行实数分布式空时编码并附加传输参考,在中继节点处利用传输参考对多径分量进行模拟合并,从而构建了一种改进型非正交放大转发协作通信系统.仿真结果证明,相对于无协作通信系统,模拟合并转发...

| Abstract: | In allusion to the complexity channel estimation of cooperative communication
system over frequency-selective fading channels,a scheme of analog combinatio
n and forward ultra-wideband (UWB) cooperative communication is proposed. The tr
ansmitting symbol is coded by real space-time code and the transmitted reference
is appendded at source node,the multipath components are analog combined by a
pplying the transmitted reference at relay node, then a modified non-ort
hogonal amplify-and-forward cooperative communication system is construed. The s
imulation results show that compared to the non-cooperative communication, the t
ransmission ability of analog combination and forward cooperation system can be
efficiently improved without channel estimation. |
