  1. And then facing the problem of the channel estimation of the adaptive modulation system, we conclude out the channel estimation algorithms on maximum likelihood ( ml ) estimation and maximum a posteriori ( map ) estimation under the condition of flat fading channel and selective fading channel in detail. to meet flat fading channel, we simulate the relationship of the ratio between the error covariance in map estimation and ml estimation and pilot symbol message length. the conclusion can be drawn from these results

    接著，對自適應調制系統中的通道估計問題難點，詳細推導了平衰落通道條件下和選擇性衰落通道條件下最大似然（ ml ）估計和最大后驗概率（ map ）估計演算法，針對平衰落通道，我們模擬了map估計和ml估計的方差與導頻符號長度的關系，模擬結果表明，錯誤方差受多譜勒頻率的變化影響最大，並且對實際的自適應調制系統，導頻符號長度的取值超過20個符號長度時， map通道估計明顯優于ml通道估計。
  2. At first, the text is segmented to words and converted to a sequence of part - of - speech tags ; then based on the pos tags sequence parameters and phrase - break distance information from training, markov model is used to get the most likely phrase break sequence

    首先，文本進行分詞，並轉換為一列由詞性標記所組成的序列；然後使用馬爾可夫模型，利用人工標注數據庫訓練詞語連接處詞性標注序列的概率分佈和連接類型序列的距離信息，得到輸入的詞性標記序列對應的具有最大似然概率的連接類型序列，最後利用后處理規則進行適當的糾錯。
  3. It contributes to the deeper comprehesion of these probability distributions, affords more detailed theoretical basis for further studying and simulating satellite mobile channels, ? theoretical analyses and discussions of the models which are often used in the study of the propagating characteristics of satallite mobile channels are given ; meantime, some discussions on the work of model simulations are also given, ? incorrect derivation of the equality between c. loo model and corazza model in some other papers is pointed out. via the conception of received power, we derivate that in the rural environments these two models really have the equal relationship by the way of theoretical derivation and simulatant fittings. therefore, it is able to use corazza model in studying the characteristics of satellite mobile channels in the rural environments and able to avoid the iterant work of modeling, in order to enhance the efficiency and accuracy of research work, ? detailed processes of simulating lutz model by using matlab6. 0 _ simulink4. 0 and the results of comparisions are given

    本文包含有以下的主要內容： ?對衛星移動通信通道傳播特性研究中常用的三個概率分佈給出了詳細的推導過程；以便對這幾個在衛星移動通信通道傳播特性的研究中常用的概率分佈函數有更深的理解，對進一步研究衛星移動通信通道傳播特性和對通道的建模提供了更為詳盡的理論基礎； ?對衛星移動通信通道傳播特性的研究中常用的通道模型進行了理論上的分析和討論，並對衛星移動通信通道建模的研究工作提出了一定的看法； ?指出了以前的文獻中關于c . loo模型和corazza模型的等同性的證明錯誤；並從接收信號功率的角度出發，通過理論推導及模擬曲線擬合重新證明了在鄉村環境下，這兩個模型的確是具有等同性的；從而在對鄉村環境下的衛星移動通信通道傳播特性進行研究時，可以只採用corazza模型來對實際的通道進行建模，這樣可以避免重復的建模工作並提高研究工作的效率和準確性； ?給出了lutz模型在matlab6 . 0 _ simulink4 . 0環境下的軟體模擬實現的詳細過程和整體模擬測試的對比結果，保證了該模型在硬體實現時的可靠性和可行性，從而可以將它們應用於指導模型的硬體模擬實現並可以降低硬體實現時的風險。
