Abstract :
The concept of the Generalized Phase Spectrum (GPS) TDE is put forward. The relation between the GPS TDE and the GCC TDE is derived. A multipath signal model is considered. The method of Amplitude Square (AS) weighting for TDE is proposed and the comparison between the AS TDE and the Phase Data (PD) TDE is made in the multipath environment. The results of theoretical calculation and computer simulation experiment show that the performance of the AS weighting TDE is superior to that of the PD TDE.
