This paper presents a new smart antenna algorithm. Based on the characteristic that in CDMA system desired signal is much larger than other signals after despreading, the algorithm uses eigenvectors of each autocovariance matrix of the first element and one of the other elements to form the weight vector.

本文根据CDMA系统的特点提出了一种新的智能天线算法，该算法利用CDMA系统解扩后有用信号远大于其他用户信号的特点，通过求得每根天线与第一根天线的信号相关矩阵的特征向量来确定智能天线的加权系数。

This section simply introduces the basic principles of the conventional analysis of time series (mean, variance, standard deviation; covariance and correlation coefficient; autocovariance and autocorrelation coefficient), frequency spectrum analysis and wavelet analysis.

本文简单地介绍了传统时序分析（包括平均值、方差和标准差；协方差和相关因子；自协方差和自相关因子）、频谱分析和小波分析的基本原理。

In this paper we use the nonparametric MLE of the marginal distributions of Xt and Yt to construct estimates of the mean, autocovariance and autocorrelation functions of the original signal process {Xt}.

本文在左截断数据模型下估计平稳信号过程的{Xt}均值，自协方差函数，和自相关系数。

After applying the Phase-randomized surrogate algorithm to create surrogate data, three test statistics methods, which include KS test, the third-order autocovariance and the asymmetry due to time reversal, are employed to determine nonlinear of five kinds signals.

通过对各类信号的数值实验及与传统使用的高阶自相关量以及时间反演不可逆量对比结果表明，KS检验是一种有效、稳定的非线性检验统计量，对噪声信号具有较强的抗噪能力，而对非线性信号具有较高的敏感性。
