| Abstract: | 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. |
