Abstract: Echo path estimation in echo cancelling for teleconference system is a problem in double talk condition. The correlation processing algorithm was defined by the authors to solve this problem. In this paper, a new fast implementation in the frequency domain with correlation initialization and step size normalization is introduced. The new frequency-domain ECLMS (FECLMS) algorithm requires only 2.7% of the ECLMS computational loads. The new algorithm is superior as compared with conventional one in double-talk with speech signal.
