本文從白石水庫泥沙模型試驗入手，模型試驗首先通過模型糙率和模型選沙驗證試驗，說明模型製作和選沙是合理的；然後開展初設方案30年運用水庫淤積試驗，並與數模計算對比，基本相同；試驗結合工程初期運用實際情況，進行了兩個不同初期運用水位方案的對比試驗，從兩個方案試驗結果看，初期運用的兩個方案淤積總量差別不大，而從效益看，方案二優于方案一。In this thesis, first, we present the theory of sess system, the generation of the sess spreading code and its characteristics and the acquisition theory of conventional spread spectrum communication system. an efficient acquisition scheme based on periodically transmitting the synchronization head, which is composed of binary chaotic codes, using the matched filter and automatic decision threshold - level control based on a so - called constant false alarm criterion for sess system is present. the acquisition model of sess system is built and simulated in the awgn channel, the raleigh fading channel and imulti - address interfere condition
本文首先概述了自編碼擴頻通信的原理、自編碼擴頻序列的產生方法及其特性和擴頻通信系統編碼同步的理論，然後針對自編碼擴頻通信系統提出了擴頻序列捕獲方案:周期性地加入混沌序列同步碼，並採用恆虛警率匹配濾波器捕獲法;在加性白高斯噪聲通道、瑞利衰落通道和多址干擾情況下進行了模擬，分析了各種捕獲性能:在選擇性能最優的混沌序列、適當的序列長度、虛警概率及門限值的情況下，可以獲得較短的捕獲時間和較大的捕獲概率。Roving reporter cindy campbell sets out to find a hard news story in the middle of television sweeps. she soon uncovers an outrageous onslaught of globe - threatening developments including alien invaders, killer videotapes, freaky crop circles, prophecies of the one, eerie - eyed children, ambitious white rappers and even a run - in with michael jackson. faced with conspiracies of massive proportions, and a crew of very strange people following her around, cindy must fight to stop evil from taking over the world yet again
