无线传感器网络中V-BLAST接收方案性能的研究

Study on performance of V-BLAST receive scheme in wireless sensor network

由于无线传感器网络部署的地区环境复杂、电池难以更换,因此用传感器能量的高效使用来延长整个网络的寿命,是传感器网络需要考虑的重要方面。在介绍了无线传感器网络中基于虚拟MIMO通信系统的两个模型方案的基础上,针对能量效率高的V-BLAST方案由误码率与信噪比的研究对节省传感器节点的能量进行了分析。

As wireless sensor network is deployed in the complex environment and the batteries are replace, so it is very important that energy- efficient sensor model should be used for prolonging difficult to the whole network life. On the basis of introduce of two model scheme of virtual MIMO system in wireless sensor network, this paper presents energy- efficient V - BLAST scheme analysis about energy of sensor network node through studying the BER and SNR.
