estimation technic 《英文msh詞典》Estimation Technic ; [入口詞] Estimation Technic ; [主題詞] Statistics ; [英文釋義] The science and art of collecting,summarizing,and analyzing data that are subject to random variation. The term is also applied to the data themselves and to the summarization of the data.
And then, adopting the same model, cyclic moment estimation statistic of different orders are constructed respectively, large sample variance expressions of the estimator through theoretic analysis are derived, as well as the constraint relation of estimator performance and noise statistical characteristic . the curve of estimation performance is obtained through monte carlo simulation test, which proves the related conclusion derived 然后,論文同樣以加性和乘性噪聲聯(lián)合干擾下的復(fù)諧波信號和復(fù)線性調(diào)頻信號為觀測模型,分別構(gòu)造了基于不同階次的循環(huán)矩估計量,從理論上推導(dǎo)出了估計量的大樣本方差表達(dá)式,分析了估計量性能與噪聲統(tǒng)計特性的約束關(guān)系,通過monte-carlo仿真試驗得到了估計性能的曲線,驗證了推導(dǎo)的有關(guān)結(jié)論。
At last, we study the fixed estimation statistics of navigation and positioning parameter, compare positioning accuracy of the condition estimation with that of the fixed estimation, and point out interrelation of them . 6 ) after investigating the two methods of increasing the success probability, a new method of increasing success probability is presented . based on the quality of ambiguity estimators, the new method carries out the ambiguity ordering process, chooses ambiguities by estimators " accuracy, and goes on ambiguity decorrelation process using those chosen ambiguities with high accuracy 6)研究了兩種提高整周模糊度估計成功概率的方法,提出了一種提高整周模糊度估計成功概率的方法,該方法是在模糊度去相關(guān)變換過程中,根據(jù)各個模糊度估計的質(zhì)量,對模糊度估計元素進(jìn)行排序選擇,選擇那些估計精度高的模糊度估計元素繼續(xù)進(jìn)行模糊度去相關(guān)變換,通過數(shù)學(xué)分析和仿真證明了這樣的處理過程可以得到較大的成功概率。
