TDO怎么读

In non-line-of-sight propagation ( NLOS) environment, the location performance of Chan ′ s algorithm is significantly degraded because the time difference of arrival ( TDOA) measurement is biased by a NLOS error.

在非视距传播（NLOS）环境中，到达时间差（TDOA）测量值受NLOS误差的影响而产生偏差[1]，使得Chan算法[2]的定位性能显著下降。

With adding a main station connected with the reference station by a fiber, the time synchronization between the reference stations of the TDOA algorithm was achieved and the position frames were send. 3.

通过增加一个与参考站以有线光纤相连的主站，实现了TDOA算法所需要的参考站之间的时间同步，完成定位信息帧的发送。
