  1. 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信的原理、自編碼擴頻序列的產生方法及其特性和擴頻信系統編碼同步的理論,然後針對自編碼擴頻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,並採用恆警率匹配濾器捕獲法;在加性白高斯噪聲、瑞利衰落和多址干擾情況下進行了模,分析了各種捕獲性能:在選擇性能最優的混沌序列、適當的序列度、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。
