| Abstract: | The problem of TDOA estimation of wideband signal is considerd.The signal model of TDOA estimation is given,the cyclostationarity of wideband signal is analyzed and a TDOA estimation method based on the cyclic cross-correlation amplitude is constructed.Finally,the performance of the estimator is given through computer simulation,and the performance of the method of this paper and generalized cross-correlation method is compared.The simulation results show that the cyclic cross-correlation method has a good performance. |
