摘要
简要介绍了广义相关法等几种基本的时间延迟估计方法，着重分析论证了这几种方法之间的相互关系．结果表明：广义相关法与广义相位谱法是等效的，广义相关法是广义双谱法的特例，基于ＬＭＳ自适应横向滤波器的自适应法是迭代实现的广义相关法。
This paper introduces several kinds of methods for time delay estimation (TDE) and demonstrates the relationship among the methods. The results show that the generalized correlation TDE method is equivalent to the generalized phase spectral TDE method. The generalized correlation TDE method is a special case of the generalized bispectrum TDE method. LMSTDE is the iterated realization of the generalized correlation TDE. The TDE method of parameter modeling can be realized by LMS adaptive filter.
