  1. The basic idea of this method is to produce particles from the posterior densities, and these weighted samples provide approximations to the densities. in this dissertation, sequential monte carlo method and its applications in communication are investigated. firstly, its basic idea, method and improved method are introduced, then induce the bound of particles, which determines the performance of the system, and the more particles are chosen, the higher computation is done, finally, a new detector based on new importance function is proposed, which deals with the joint channel estimation and detection in flat fading channels

    首先介紹了它的基本思想、基本方法、及當前研究現狀；在此基礎上推導出樣本數選擇的界，樣本數的選擇決定了系統的性能，但是若選的太多，計算復雜度也會隨之增大，因而給出這個界是十分有意義的；最後提出了一種基於新的重要函數的檢測器用來解決平坦衰落通道下的聯合通道估計和檢測問題，並通過模擬證明了我們提出的新檢測器的有效性。
  2. Due to its flexibility, the lrt system can be designed to match both the physical environment and transport demands as well as to provide an alternative choice with quality service. all these factors have contributed to the phasing - out of the old streetcar systems. beginning in the mid - 1970s, light rail transit systems have enjoyed a period of sustained growth, not only providing public transportation but also contributing to the renewal of declining city districts, reutilizing unused rail lines, and providing impetus to local economic development

    使得有軌電車自1970年代中期，以輕軌運輸的新風貌漸漸復興，不僅擔負公共運輸功能，更常結合老市區都市更新、舊鐵道再利用、促進經濟再發展的聯合開發計畫，吸引民間投資參與建設，透過由街道面進出的低月臺車站、無欄柵式收費制度、造型流線超低底盤車輛、軌道沿線綠化設施等設計，在都市環境改善與都市永續經營上，充分發揮凈化、綠化、人性化、地標化等效益，發展至今估計全世界輕軌運輸系統路網數目已達約400個左右。
  3. The estimation of additive and dominance effects through qtl analysis by one - dimensional search while ignoring epistases showed similar accuracy to that by two - dimensional search by including epistases. existence of epistases could decrease the precision for the estimation of additive and dominance effects. the estimation of genetic main effects would be biased if ignoring the interaction effects of qtl x environment ( qe )

    忽略上位性效應的一維搜索qtl分析對加性效應和顯性效應的估計精度與包括上位性的兩維搜索qtl分析對這兩種效應的估計精度相差不大，上位性的存在可能會降低對這兩種效應估計的精度；忽略qtl環境（ qe ）互作效應會導致對遺傳主效應的有偏估計，而包括qe互作效應的多環境聯合分析能夠提高對遺傳主效應的估計精度。
  4. The method that increases the attitude accuracy of strapdown inertial attitude and heading reference system ( siahrs ) with the infromation from inertial measurement unit ( imu ) its own is studied. according to the design idea of damping network in platform type, damping kalman filter in siahrs is designed to enhance the attitude accuracy via integrating attitude calculated by common siahrs and that estimated by accelerometers. in order to evaluate the effectiveness of damping attitude, the vehicle ' s movement should be detected in real - time. for this reason, the state chi - square test is employed in the damping kalman filter, and the failure detection vector are tested, which improves the sensitivity and reliability of failure detection. finally, static and dynamic experiments of actual system demonstrate the effectiveness of the proposed method

    本文探討了如何利用慣性測量組合本身的信息來提高捷聯航姿系統的姿態精度.根據平臺式阻尼網路的思想，設計了捷聯式內阻尼卡爾曼濾波器，將慣導系統捷聯解算獲得的姿態與加速度計估計的姿態進行組合，在系統非加速度狀態下，提高了姿態輸出的精度.為了實時監測系統的運動狀態從而判斷內阻尼姿態的有效性，本文成功將狀態2檢驗法應用在內阻尼卡爾曼濾波器中，設計了基於2個狀態傳播器的故障監測器，並通過對故障檢測向量元素的檢驗代替對整個向量的檢驗，提高了故障監測的靈敏度和可靠性.最後，實際系統的動靜態實驗驗證了本文所提出的方法的有效性
  5. Combination algorithm fully use the advantage of the ukf for small noise and the upf ’ s non - sensitivity to noise, when noise increase, upf can also estimate the missile ’ s states well

    聯合演算法充分利用了ukf在噪聲較小時估計效果較好和upf對噪聲不敏感的特性，使得當觀測噪聲突然增大后，利用upf演算法仍能使導彈位置和速度誤差收斂，達到有效預警的目的。
  6. Aiming at this problem, particle filter is studied. combination filter algorithm is constituted using ukf and improved particle filter ( upf ), and missile ’ s states with noise increase are estimated

    針對這個問題，研究了粒子濾波演算法，利用ukf和改進的粒子濾波（ upf ）組成聯合濾波估計演算法，可以有效估計具有噪聲增大時導彈主動段運動狀態。
