Abstract: Acoustic echo cancellation using various adaptive algorithms have been suggested by many researchers. A particularly interesting approach uses a new implementation of the LMS/Newton algorithm. It is reported in [1] that software simulations show good results of acoustic echo cancellation in a teleconferencing setup. Based on this new implementation of the LMS/Newton algorithm, software simulations and real-time implementation of acoustic echo cancellation in a teleconferencing-like environment are carried out. Software simulations are conducted to reconfirm the results presented in [1] and, also, to examine the effect of various involved parameters. A DSP card is used to carry out real-time realization of the proposed LMS/Newton algorithm. Real-time realization of the normalized LMS (NLMS) algorithm is also implemented for comparison.
