sight locating 中文意思是什麼
sight locating
解釋
觀察定位法-
In 3g communication system, the most promising location method was the locating arithmetic based on the time of arrival and the time difference of arrival ( toa / tdoa ) of signal, or the angle of arrival of signal ( aoa ). however, either the arithmetic based on toa or that based on aoa was badly affected by the none line of sight ( nlos ) phenomenon
在第三代移動通信系統中，最有前景的定位方式是基於信號到來時間/時間差（ toa / tdoa ）或信號到來角（ aoa ）的定位演算法。但不管是基於信號到來時間的演算法還是基於信號到來角度的演算法，定位信號的非視距傳播效應（ nlos ）都會對其造成嚴重的影響，在影響移動定位精度的諸多因素中nlos效應被公認為是最主要的因素。
