視滑距 的英文怎麼說
中文拼音 [shìgǔjù]
視滑距
英文
apparent slip-
A position estimate method is proposed, in which the los reconstruction and smoothing technique are combined to mitigate the influence due to nlos propagation
提出了一種將視距重構與平滑處理相結合減小非視距傳播影響的定位方法。At first, by using the feature that the excess delays of nlos propagation follow the exponential distribution, the los propagation parameters are reconstructed and the toa parameters measured from all bs are preprocessed. then, the ms ' s position is estimated by the los locating algorithm with the preprocessed data. finally, to mitigate the effect of the errors in reconstructed parameters, the estimated results are smoothed
首先,利用非視距傳播時延服從指數分佈的特點,對不同基站一次測量的數據進行預處理,重構視距傳輸參量;然後,對處理后的數據採用視距定位演算法估計移動臺位置;最後,對估計結果進行平滑后處理,以減小重構出的參量誤差的影響,進一步提高定位精度。
