摘要 在无线传感器网络(WSNs)中,由于节点资源受限,一般不具备多天线,为了充分利用多入多出(MIMO)技术的优点,组成虚MIMO结构成为现实可行的技术。分析了MIMO技术特点,在给出的虚MI-MO结构的基础上,提出了WSNs虚MIMO技术要解决的主要问题,并给出了解决方案。 Owing to the limited node resources, there is generally only one antenna in wireless sensor networks (WSNs). So it is possible to set up a virtual MIMO structure in terms of the advantages of MIMO technology. Mter analyzing MIMO technology, by firstly setting a virtual MIMO structure, the main problems of MIMO technology in WSNs are pointed out, and then their respective solutions are proposed.
