  • 摘要: 针对资源有限、存在信道退化的无线传感器网络(Wireless sensor network, WSN),基于最大似然估计(Maximum-likelihood estimation, MLE)提出一种信道感知的目标定位方法. 把传感器观测数据量化为M位二进制序列,经过衰落信道多跳中继到达融合中心. 中继节点采用二元解码-前向中继策略,中继输出是被信道污染的中继信号的估计值. 在Rayleigh信道衰落和高斯信道噪声假设下,结合无线信道衰落的统计知识和解码策略, 推导了观测数据的似然函数,得到目标位置的最大似然估计. 此外,还推导了估计器性能的后验克拉美-罗下界(Cramr-Rao lower bounds, CRLB). 仿真结果表明,信道感知的方法能够减缓由于信道衰落和噪声所带来的定位性能的退化.
