non-line-of-sight error

The distance measurement errors include errors of measuring noise and non-line of sight, of which NLOS error is the main source of error in location estimation.

距离测量误差包含测量噪声和非视距误差两部分，其中非视距误差是位置估计的主要误差来源。

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.

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。
