描述了确定三次样条曲线拟合参数的方法。参数包括节点数、节点位置和与系统误差相联系的权重。
The parameters including knot Numbers, knot positions and the weights associated with the systematic errors in the cubic spline curve fitting method were discussed.
在无线传感器网络定位中，节点精确定位面临的一个主要问题是信号的非视距传播，非视距误差是节点定位误差的主要来源。
A key obstacle to high accuracy location is the Non Line of Sight (NLOS) transmission of signal in wireless sensor network node localization. NLOS error is the main source of location error.
