Analysis of Serial Acquisition of Two Dimensional Spread Spectrum System in Multipath Fading Channels

  • 摘要: 該文給出了一種二維擴(kuò)頻矩陣的時間同步方法，分析了此方法的捕獲概率和虛警概率；在不同歸一化門限條件下，給出了數(shù)值結(jié)果。分析結(jié)果表明，經(jīng)映射的二維擴(kuò)頻系統(tǒng)等效為一維擴(kuò)頻系統(tǒng)，采用一維擴(kuò)頻的同步方法能使二維擴(kuò)頻系統(tǒng)獲得良好同步性能，且方法簡單。
    Abstract: In this paper, a method of time synchronization of 2D Spread Spectrum (2DSS) system in multipath fading channels is proposed. The detection probability and false-alarm probability are analyzed and also the numerical results on condition of different normalized thresholds are presented. The theoretical results show that the mapped 2DSS system is equal to the 1D Spread Spectrum (1DSS) system. So the synchronization algorithm in the 1DSS system can be used in 2DSS system, and good synchronization performance can be obtained and its algorithm can be simplified.
