摘要
提出了一种自适应相位谱时间延迟估计方法该法利用时域或频域ＬＭＳ自适应滤波器，自适应地实现Ｒｏｔｈ处理器即维纳滤波器。
Proposes an adaptive phase spectrum time delay estimation method.This method realizes the Roth processor or Wiener filter by using the LMS adaptive filter in time domain or in frequency domain.The time delay estimate is obtained from the optimal vector of the adaptive system.This method has a good estimation precision and some ability on interference resistance.When it is realized in frequency domain,the calculation complexity can be reduced effectively.
