中文摘要：
提出一种基于虚拟多天线技术的分布式和协作的无线传感器网络,分析了该虚拟多天线无线传感器网络的性能。同点到点的无线传感器网络相比较,在天线传输信号能量相同的情况下,虚拟多天线无线传感器网络的误比特概率（BER）更小;或者在同样误比特概率情况下,虚拟多天线无线传感器网络的天线传输信号能量更低。这些特性能够提高无线传感器网络的性能或延长无线传感器网络的使用寿命。
英文摘要：
A virtual multiple-input multiple-output （MIMO） based communication architecture is proposed for distributed and cooperative wireless sensor networks, The performance of this virtual MIMO wireless sensor network is analyzed. Compared with the end-to-end wireless sensor network, the bit error rate （BER） of virtual MIMO wireless sensor network is smaller or the energy consumed by each sensor in the virtual MIMO wireless sensor network is saved under the same BER performance. These properties can improve the performance or extend the llfe of wireless sensor networks.
