The interpolation approaches to the shape recovery of a speech signal in transmission over packet switched communications networks are proposed. The samples of a signal jkagments are mixed and transmitted in correspondence with standard procedure of packet-switched transmission. After reception a reverse permutation is made. In the case of packet losses missing samples are separated by several samples of the source signal. Correlation properties of the signal are used for the recoveiy samples due to the Jirst-and second-order non-adaptive and adaptive interpolation. For the loss of 25% packets and second order adaptive interpolation are 2-4% error distribution range has been achieved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
