Echo path estimation in echo canceling for teleconference system is a problem in double-talk condition. The correlation function based algorithms were defined by the authors to solve this problem. In this paper, in order to improve the convergence speed of correlation function based algorithm, we propose a new modified proportionate step-size adaptation(More)
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 proposed a new promotional algorithm with fast convergence speed - proportionate extended correlation LMS algorithm (PECLMS). The idea of the PECLMS(More)
In this paper, the smart acoustic room (SAR) system is presented for background signal cancelling in the car. That is, the sound sign from loudspeakers of car will be diminished at the microphone position of the hand-free telephone. This is realized by robust estimation algorithm for well control of the acoustic impulse responses in car. Therefore, unwanted(More)
