  1. This paper can put into four parts ? this first part is the description and theoretical analyses of source coding, which focus on the research of optimizing equal quantization ? the second part presents the theoretical description of joint channel - source coding, which focus on the research of combined channel - source coding o the third part is about the application of combined channel - source coding to two different channel models, binary symmetric channel and cdma channel o in this part, two different coding designs are given according to different characters of these two channels ? and the last part is the description of simulation of combined channel - source coding ? most of my work are about two parts, one is to find the most appropriate quantization steps and centroid points of separate channel - source coding, another is to simulate the combined channel - source coding ? comparing the simulation results of separate channel - source coding and combined channel - source coding, the characters of joint channel - source coding are given

    本論文可以分成四部分：第一部分給出了信源編碼的基本概念和理論分析，重點放在最優均勻量化編碼的研究方面；第二部分給出了通道?信源聯合編碼的原理敘述，重點放在復合式通道?信源編碼的分析研究上；第三部分將通道-信源聯合編碼原理應用在兩種噪聲通道上：離散無記憶通道和cdma通道，並根據兩種通道的不同特點詳細描述了兩種相應的編碼設計方案；第四部分給出了復合式通道-信源編碼的模擬結果以及對結果的相應分析。
  2. First, there is no specific parameter for quantization ; second, the effects of transaction fee are ignored ; third, because these models are equilibrium models, they can ’ t reveal many of the prosperities observed in empirical markets, such as fat - tails, long - range correlations in volatility, etc. in the process of i study financial economics, when the teacher xu jia - gen to speak the price of the stock market to visit the distance examination and the artificial intelligence models, i think, if mathematics combines with the calculator. ( i studied mathematics four years in the southwest normal university ). the stock market price exercise regulation will easily confidence

    首先，沒有用具體的參數來量化股市的行為，其次，它們都忽略了交易費對股市的影響，第三，由於這些模型都是均衡模型，無法展示實際市場回報分佈的特點，諸如「肥尾」現象、集群波動等。在我學習金融經濟學的過程中，徐加根老師講到股票市場價格的遊程檢驗與人工智慧模型時，我想，如果數學與計算機的結合（在西南師范大學學習了四年數學） ，股票市場價格運動規律就容易把握了。
  3. As we all know, the diagonalization of hamiltonian is an important procedure in solving the many - body problem in second quantization frame. usually we used the bogoliubov - valatin transformation method to diagonalization the hamiltonian that we were interesting in

    眾所周知，二次量子化框架下，多體物理系統哈密頓量的對角化步驟是非常重要的，通常我們都是使用bogoliubov - valatin變換對角化方法將被研究系統哈密頓量對角化。
  4. In this paper, we first investigate the impurity effect ( ba2 + ) on the dielectric and phase transition properties in srtio3 within the framework of the transverse - field ising model ( tim ). then a possible coupling mechanism between the magnetism and dielectric properties in eutio3 is discussed and the magnetic influence on the frequency of the soft - phonon mode is investigated via the heisenberg model, soft - mode theory under the mean field approximation, the second quantization theory and the perturbation theory. and we proceed further investigation on eu1 - xbaxtio3 of

    我們發現baxeul _ xtio3 （ o 『 x 『 0 . 2 ）的介電常數和由內察的偏置場導致的電極化除了隨雜質濃度產生相應的變化，同時在磁和介電性質的藕合作用影響下在低溫下偏離通常的量子順電體行為，在尼爾溫度附近出現異常，且磁場通過對最近鄰自旋關聯的作用來影響介電常數和電極化。
  5. In the second part of this work, according to cosine function ' s cycle property and using the quantization square choosed by international standards such as jpeg, h261 / h263, mpeg1 / 2, a kind of dct coding algorithm that based on tabling is put forward

    第二部分採用jpeg 、 h261 h263 、 mpeg1 2等國際標準中所選擇的量化矩陣，根據餘弦函數的周期性提出一種基於查表的dct編碼演算法。
  6. In case where long - range communication is needed, spatial diversity blind equalizer ( sdbe ) is an effective way to improve snr and suppress distortion. joint carrier phase recovery with sdbe using second order digital phase lock loop is presented to track the doppler shift, and a kind of quantization method is used to reduce the complexity of the multi - channel algorithm. its performance is very similar to the original one

    模擬結果表明，採用二階數字鎖相環的空間分集均衡演算法的跟蹤性能超過了採用一階鎖相環和未加鎖相環的演算法，可有效補償由於水聲通道時變而引入的載波相位快速變化；採用誤差量化的演算法和原演算法的收斂和踉蹤性能都很接近。
  7. The embedded bw also successfully survives cropping, filtering, noise and multi - watermarking etc. the new ideas the thesis proposed are : first, frequency - based watermarking idea using toral automorphisms is really a novel one, although, in the literature, there are some waterniarking schemes using toral autpmorphisms, all of which are based on space ; second, some improvements of the quantization function contribute to the algorithm ' s performances to some degree

    另外該演算法對圖象裁剪、濾波、噪聲和多重水印處理等都具有較強的魯棒性。本文提出了兩個新思想：第一，雖然現有文獻已經提出了利用環形自同構映射的數字水印處理演算法，但這種演算法是基於空域的，而利用環形自同構映射基於頻域的水印處理演算法，目前文獻上未見報道。
  8. In the second chapter, researches celp that is the theory base of g. 729a standard. celp uses speech mathematical model, linear prediction and vector quantization

    729a標準的理論基礎，它綜合利用了語音信號的數學模型、語音信號的線性預測分析和矢量量化等技術。
