Abstract :
Echo path estimation in echo canceling for teleconference system is a problem in double-talk condition. The correlation-processing algorithms were defined by the authors to solve this problem. In this paper we propose a new algorithm with very low computational complex, which is called Hartley transform extended correlation LMS algorithm (HECLMS). The computer simulation results support the theoretical findings and verify the robustness of the proposed HECLMS algorithm in the double-talk situation.
