Robust time-delay estimation in highly adverse acoustic environments

A robust time-delay estimation algorithm in situations where a large amount of additive colored noise and re-verberation was presented. This algorithm estimates TDE through blind identification of room impulse response in order to eliminate the effect of reverberation,and uses eigenvalue decomposition of a lagged correlated matrix to avoid the ef-fect of colored noise. Simulation results show that the proposed algorithm can give robust time-delay estimation when colored noise and reverberation exist.
