MIMORadarDOAEstimation
MIMO雷达模型下一种子空间谱估计方法,采用过估计的方法,以避免信源数估计的问题,直接对数据协方差矩阵进行变换,从而构造了信号子空间投影矩阵和噪声子空间投影矩阵,不需要像经典的MUSIC一样对其进行特征分解,完全避开了在一般非理想情况下MUSIC算法必须面对的识别小特征值与大特征值的麻烦,降低了复杂度,而且该方法不受快拍数的影响,在相干源情况下也能准确的估计目标的入射角,不会出现伪峰。(A subspace based DOA (Direction-Of-Arrival) estimation method for MIMO (Multiple-Input Multiple-Output) radar is studied in this paper. By transforming the data covariance matrix, we can construct the projection matrix of signal subspace and noise subspace. The computation complexity of the algorithm is reduced as it does not need to perform eigendecomposition. By using the over estimated theory, this algorithm avoid estimating the number of signal sources and can keep a good estimate performance in the case of lower SNR (Signal-to-Noise Ratios) and multi-target. )

WSN 质心定位算法 Centorid Algorithm
加经典参考文献
A: 如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
未知节点利用邻居锚节点进行定位,没有邻居锚节点的未知节点无法定位。
B:
如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
未知节点一旦被定位就充当起锚节点的功能,向周围邻居发送自己的估计坐标信息
未知节点把已经定位的未知节点与锚节点同等对待
C:
如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
有邻居锚节点的未知节点只利用邻居锚节点进行定位,没有邻居锚节点的未知节点才利用已经定位了的邻居未知节点进行定位。(WSN centroid localization algorithm Centorid Algorithm
A: If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Unknown node using the neighbor anchor nodes to locate, no neighbors anchor nodes and unknown nodes can not be located.
B:
If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Unknown nodes are positioned on as soon as the function of anchor nodes to send their neighbors estimated coordinate information
Unknown unknown node to node already positioned anchor nodes treated equally
C:
If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Of the unknown neighbor anchor node the neighbor nodes are only positioned anchor nodes, )
