  1. The following algorithms have been proposed and tested in the thesis : 1 frequency selective fading : combine the isomorphism between the input space and the output space and propose a new approach to blind equalization of the channel. compared with conventional methods, the new approach offers lower computational complexity, better performance, and more robust against the over - determination of the system order ; 2 time selective fading : a new approach to the equalization of time selective channel based on the zero - forced equalizer is proposed which is more simple in its structure of algorithm ; 3 time - varying channel : using the instantaneous mean value changes of the output signal to extract the information of channel variations and model it using ar model, kalman filter is then employed to track channel variations, it bears faster ability in tracking the variation of tv channels ; based on the isomorphism between the inputs and the outputs and some of the approaches using in mimo system, a new algorithm of equalization of simo time - varying channel is proposed, which also share the merits of being robust against the over - determination of the system order ; model the time - varying channel using the multi - resolution decomposition wavelets, and then a blind identification method based " on the model is proposed ; at last, a new model for equalization and identification of mimo system is proposed

    主要工作在以下幾個方面： 1 、針對頻率選擇性衰落通道：結合輸入輸出空間同構關系提出一種新的頻率選擇性通道均衡方法，與傳統方法相比，該方法計算量更小，收斂速度更快，性能更優，且對系統階次的過確定表現穩健，具有實際均衡應用價值； 2 、針對時間選擇性衰落通道：提出一種基於迫零均衡的時間選擇性通道均衡方法，演算法結構簡單； 3 、針對時變色散通道：利用瞬態均值曲線提取通道時變信息，對之ar建模，利用卡爾曼濾波器跟蹤時變通道抽頭變化，可以快速跟蹤通道變化；基於輸入輸出空間之間的同構關系以及多輸入多輸出系統的處理方法，提出了新的單輸入多輸出色散時變通道均衡與識別演算法，同樣具有對通道階次過確定保持穩健的優點；結合小波多解析度分析提出一種基於小波模型的通道盲識別演算法；研究時變的多輸入多輸出系統的盲均衡與盲反卷積問題，給出一種時變系統處理模型。
  2. The sequence is : non - classical ng supersaturated solid solution spinodal decomposition the variation in precipitation mechanism of 8 " phase in intermediate region is systematically investigated firstly, and it is found that with the increase of composition the precipitation characteristic transforms from that of metastable to instable region gradually

    首次發現l12有序疇之間首先形成較寬的重合位置點陣，隨時間延續，重合位置點陣逐漸向ll :結構轉變，在兩有序疇之間形成反相疇界，隨后，由於合金發生分解，反相疇界被有序一無序界面替代。
  3. And one important conclusion is : a finite t0 - measure defined on a generated tx - tribe ( [ 0, ] ) has a jordan decomposition if and only if it is of bounded chain variation, where t is a frank t - norm

    其中一個重要的結論是：定義在生成的t _ ?族（ [ 0 ， ] ）上的有限t _ 0 ?測度有jordan分解的充分必要條件是它具有有界鏈變差，其中t _是一個frank三角模。
  4. Organism decomposition rules of msw are generalized and an equation to evaluate the variation of organic substance with time ( depth ) is proposed at the first time in this thesis. the equation is verified when compared with the results from field - test

    本文總結了填埋體有機質的分解規律，創造性地提出了填埋體中有機質隨時間（深度）變化的公式，並用現場測試結果進行了驗證。
  5. Top - down domain decomposition process modeling and decomposition, variation - oriented analysis, policy and business rules analysis, and domain specific behavior modeling using grammars and diagrams is conducted in parallel with a bottom - up analysis of existing legacy assets that are candidates for componentization modularization and service exposure

    自頂向下的域分解（過程建模和分解，基於變更的分析，方針和業務規則分析，領域特定行為建模（使用語法和圖表） ）是同供組件化（模塊化）和服務公開候選的現有遺留資產的分析并行控制。
