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。The surface - wave theory was firstly provided by rayleigh, which can be used in even medium and many other learners developed rayleigh ' s theory and provided another theory which can be used in layered medium
瞬態面波法的理論基礎是英國學者瑞利提出的半無限彈性均勻介質中的瑞利面波理論及其後來發展起來的半無限彈性層狀介質中的頻散理論,因其具有同時可以大范圍檢測,精度好、效率高等優點,在無損檢測方面有很好的前景。
