dc.description.abstract | In this paper, we propose an improved adaptive muting method using a sigmoid function for the packet loss concealment algorithm of ITU-T G.722 Recommendation. The packet loss concealment algorithm performs an adaptive muting to prevent the generation of unnecessary noise during packet loss recovery. While muting is linearly and discontinuously performed according to packet errors, our muting approach is performed by the non-linear and continuous sigmoid function. The principal parameters of the sigmoid function are obtained based on training at which minimization between the desired signal and the reconstructed signal is performed. Experimental results show that this proposed muting technique can enhance the performance of the packet loss concealment algorithm of G.722 under various packet loss environments.
