| 摘 要： | The concept of the Generalized Phase Spectrum(GPS)TDE is put forward.The variance ofthe GPS TDE is calculated.The relation between the GPS TDE and the GCC TDE is derived.Amultipath signal model is considered.The method of Amplitude Square(AS)weighting for TDE isproposed and the comparison between the AS TDE and the Phase Data(PD)TDE is made in the mul-tipath environment.The results of theoretical calculation and computer simulation experiment showthat the performance of the AS weighting TDE is superior to that of the PD TDE.GPS TDE can effi-ciently utilize single chip FFT processor to simplify the signal processing equipment,mitigate com-putation load and raise estimate speed for TDE.
