Research on TDOA Estimating Algorithms

MA Jin-ming(School of Information Engineering,Beijing University of Posts and Telecommunications,Beijing 100876,China)  
The acquisition probability of two popular algorithms are investigated,which are based on general cross correlation(GCC) algorithm and widely used to evaluate time difference of arrival(TDOA) coefficients.A numerical algorithm is proposed to calculate the acquisition probability of GCC,which lays a basis for the comparison between these two algorithms.In order to evaluate the TDOA,one of these algorithms is correlating the input signals directly while the other correlates the two input signals with a noiseless m-sequence separately.The simulation result proves that the later has higher algorithm efficiency.
