Abstract:Adaptive multi-rate wideband (AMR-WB) speech coding algorithm is standardized by 3 rd Generation Partnership Project (3GPP) and third generation/wideband code division multiple access (WCDMA 3G) system and has several applications in mobile communication systems, audio and video teleconferencing, and digital radio broadcasting. To reduce the bit rate in AMR-WB, vector quantization (VQ) technique is used. In this paper, a self-organizing map (SOM) neural network is used instead of traditional VQ method proposed… Show more
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.
