time-varying filtering 中文意思是什麼

time-varying filtering 解釋
時間變換濾波技術
  • time : n 1 時，時間，時日，歲月。2 時候，時刻；期間；時節，季節；〈常pl 〉時期，年代，時代； 〈the time ...
  • varying : 變化的
  1. By changing the multiple time - varying fading factors of the strong tracking filter, mstkf switches between kalman filtering and strong tracking filtering

    通過直接改變強跟蹤濾波器的多重時變漸消因子， mstkf在卡爾曼濾波和強跟蹤濾波兩種工作狀態之間切換。
  2. And key technologies of mc - cdma, channel estimations and diversity combinations, are mainly studied for the application of mc - cdma. the channel estimation based on pilot carriers is analyzed, and an improved method with wiener filtering is presented. simulations of the method are carried in time - varying multi - path channel

    本文分析了基於導頻的通道估計演算法，提出了採用維納濾波平滑的改進估計演算法，並在多徑時變通道下進行了計算機模擬，對系統各參數分別對通道估計誤差和誤碼率性能的影響做了詳細分析和比較，從而證明了演算法和改進的有效性。
  3. Recently, withthe rapid improvement of performance of digital processor, sequential monte carlo ( smc ) method has a wide range of application in engineering, especially in signal processing, statistics, and econometrics etc. the time varying systems can be stated in the form of a dynamic state space model. for linear models and gaussian noise, the kalman filter provides analytical expressions for posterior filtering

    一般的時變系統都可以被看作是一動態狀態空間模型，對于線性高斯模型，卡爾曼濾波可以給出后驗密度函數的解析解；而對于非線性非高斯模型，我們則無法得到它的解析解，在這種情況下則可以使用序列蒙特卡羅方法來對其進行近似。
