| 摘 要： | 基于一种无线传感网模型，提出了一种新的虚拟MIMO结构，此结构不需要接收端协同，避免了以往虚拟MIMO结构中接收端协同的复杂性。文章从整个网络生存周期角度出发，分析并推导了在相同条件下虚拟MIMO相比SISO会有更小的能耗，此外，还考虑了基于导频序列信道估计对能耗的影响，仿真结果表明了协同虚拟MIMO比SISO情况下能量节省很多。

| Abstract: | This paper proposes a new virtual MIMO architecture, based on a model of wireless senor network. The proposed scheme does not need receiver-side cooperation and decreases the complexity of receiver-side cooperation in previously proposed virtual MIMO schemes. From the view of the lifetime of all the networks, the conclusion that MIMO need less energy than SISO in the same situation is analyzed and deduced. In addition, the effect on energy caused by the channel evaluation based on the pilot is calculated. The results of simulation show this solution agrees with the theory analysis |
