摘要

本文研究了扩频系统中常用的金码的三重相关函数(TCF)高阶统计量。提出了一种黄金序列的检测方法，并分析了基于TCF峰特征的黄金码接收机。这些接收器利用TCF并使用它进行自同步。本文研究了两种类型的TCF接收机，一种是可被3码长整除的一级接收机，另一种是可被任意码长整除的二级接收机。比较了两种接收机在加性高斯白噪声(AWGN)信道中的性能，证明了两种接收机对不同噪声水平的抗扰性。

Detection of Gold Codes Using Higher-Order Statistics

In this paper the higher-order statistics (HOS) specified in terms of triple correlation function (TCF) of Gold code which is commonly used in spread-spectrum systems is studied. A detection method of Gold sequence is presented and the proposed gold code receivers based on the peak feature of the TCF are analysed. These receivers take advantage of the TCF and use it for self-synchronization. We study two types of TCF receivers, one-stage receiver which is used with divisible by three code length and two-stage receiver which can be used with any code length. A comparison between the performances of both receivers in Additive White Gaussian Noise (AWGN) channel is performed to prove the immunity of the receivers against different noise levels.
