- This paper presents a new root multiple signal classification (Root-MUSIC) time delay estimation method based on the concept of well known propagator method (PM). The PM does not need the eigenvalue decomposition whose computational complexity is high. This method has great performance of time delay estimation under the condition of high signal to noise ratio (SNR) and need spectral peak searching whose computational complexity is very high. To address those issues, the new method is proposed. The proposed algorithm has high resolution capabilities and has lower computational complexity than conventional PM. Its computational complexity significantly reduces by using the method of finding the root of polynomial instead of the spectral peak searching and the eigenvalue decomposition. Theoretical analysis and computer simulation results show that the proposed method is effective.
