This paper focuses on the blind code synchronization approach and spreading sequences estimation algorithm. the main results can be summarized as follows : 1. both synchronous and asynchronous dsss / bpsk baseband signal models are established
本文重點是對盲碼同步和擴頻碼序列估計的研究，主要的工作成果如下: 1 、分同步和非同步兩種情況建立了dsss / bpsk基帶信號模型，並介紹了二種非合作式擴頻碼序列估計和解擴的方案。 -
Moreover two types of non - cooperative sequences estimation and despreading schemes are introduced briefly. 2. several usual blind code synchronization methods, including delay multiply ( sliding autocorrelation ), maximum norm and average noise reduction approaches are summed up and analyzed by computer simulations
2 、總結和介紹了幾種常用的盲碼同步方法，包括延遲相乘（滑動自相關）法、最大范數法、平均降噪法等，並進行了計算機模擬和分析。 -
Ancient egyptian society had a strong code of ethics and commandments to be respectful towards dwarfs, the crippled and blind. depictions of dwarfism in tomb and vase paintings, statues and other art forms are numerous and indicate that dwarfs were employed as personal attendants, animal carers, jewellers, dancers and entertainers
在埃及發現至少有50座墓碑銘，以及眾多壁畫雕像等眾多古埃及文物上對侏儒的生活和形象細致的描繪，侏儒在當時還被認為擁有諸如驅趕毒蛇這樣的神奇力量。 -

The output sinr limitations of mmse and constrained mmoe optimal filter are derived in the cirsumstance aforementioned. these limitations constitute the base of the code - aided optimal filtering and nbi estimate - subtract filtering. this dissertation summarize the recursive least squares ( rls ) algorithm, blind recursive least squares algorithm and the qr decomposing for these two algorithms
為自適應實現碼輔助最優濾波，本文系統總結了遞歸最小二乘（ rls ）和盲遞歸最小二乘（ brls ）演算法，以及兩者基於正交三角分解（ qrd ）的并行計算結構。 -
Based on ica post processing matched filter multi - user detection lets the output of traditional matched filter to initialize the ica iterations, not only the known spread information of interesting user is used to overcome the uncertainness of ica, but also the character of statistical independence is used. the simulation results show that it advances the ability of traditional detector when the signal - noise - ratio is large. keywords code division multiple access ; independent component analysis ; channel estimation ; matched filter ; blind multi - user detection
基於ica后處理的匹配濾波多用戶檢測是用傳統的檢測器的輸出來初始化ica的迭代，它不但充分利用多用戶信號的已知信息，克服了ica的不確定性問題，同時也充分利用了多用戶信號的統計獨立性，模擬實驗結果證明這種多用戶檢測演算法在高信噪的情況下，誤碼性能改善隨著信噪比的提高不斷增加。 -

The problem of signal processing for direct - sequence code - division - multiple - access ( ds - cdma ) signal over multipath frequency - selective mobile channels is considered. a new blind receiver is proposed. without the knowledge of the multiple - access interference users spreading code and the channel characteristics, the receiver achieves blind detection with prior knowledge of only the desired users spreading code and approximate timing. by using reduced rank adaptive decorrelating filter and adaptive multipath combiner which is based on decision - directed algorithm, the receiver gets the ability to combat both fading and the near - far effect at low cost. simulation results demonstrate that the proposed receiver offers high performance
本文研究多徑頻率選擇性衰落通道下直接序列擴頻碼分多址（ ds - cdma ）信號的處理問題，提出了一種新型的盲接收機.該接收機不需預知多址干擾用戶的擴頻碼，不需預知通道參數，只需已知期望用戶的擴頻碼和粗略的定時，就可以完成用戶的盲檢測.同時，該接收機通過降維自適應去相關濾波和基於判決指導的自適應多徑合併，來獲得低成本和良好的抗衰落、抗遠近效應性能.模擬結果驗證了本文提出的接收機的優良性能 -
