Abstract :
A high precision time delay estimation method is proposed based on the minimum variance distortionless response (MVDR) cross spectrum. The time delay between two sensor signals is estimated from the phase of the MVDR spectrum without maximum searching. Simulation results show the performance improvements of the proposed algorithm
