For any information source on a countable set, the limit properties of relative likelihood ratio and log - likelihood ratio of entropy with respect to the independent geometry distribution, an important problem in the information theory is discussed
摘要對任意的可列集上的信息源，探討資訊論的一個重要問題，即探討了相對于獨立型幾何分佈的熵密度似然比與對數似然比的極限性質。 -
Appropriate data compression methods are needed to assure the random nature of the information source and to enlarge its entropy. in this thesis, first, we present the theory of sess system, then the acquisition method of sess system is discussed in detail, finally, a acquisition model of sess system is built and simulated in the awgn channel, in the raleigh fading channel and in multi - address interfere condition. the simulation results show the acquisition method of sess system can be just as reliable as the conventional dsss systems
本文首先對自編碼擴頻通信的基本原理，自編碼擴頻序列的產生方法及其產生的序列的特性進行了概述，然後詳細討論了直擴通信系統中的擴頻碼的捕獲跟蹤問題，根據自編碼擴頻通信的特點，設計了其捕獲跟蹤方案，並在加性高斯白噪聲通道、瑞利衰落通道和多址干擾情況下進行了模擬。 -
Meanwhile, we also study the convergence behavior of iterative detection in different methods, which are the proposed average source entropy and the covariance matrix perturbation characterized by the variations of its dominant eigenvalue as well as the conventional approach based on the mutual information
為了分析迭代譯碼的收斂特性，本文從不同角度出發，在研究了傳統的互信息方法的基礎上，本文首次提出並使用了平均信源熵和用協方差矩陣最大特徵值表徵其抖動這兩種方法，使迭代過程的收斂分析變得簡單方便。
