Performance comparison of Adaptive algorithms for multiple echo cancellation in Telephone network



เครือข่ายนักวิจัย+ผลงานวิจัย (full screen)


In this paper presents the comparison of the performance of the variable step-size LMS adaptive algorithm and the fixed step-size LMS adaptive algorithm for cancels Multiple echoes signal in Telephone networks. The core of this paper is a multiple delay estimator, which estimates and distributes delays to each individual fixed length short echo canceller. It is shown that the variable step-size LMS adaptive algorithm yields the performances over the fixed step-size LMS algorithm. Computer simulation results are provided to confirm the performances of the variable step-size LMS algorithm. ©ICROS.
