摘要

With increasing demand of wireless and Internet accesses, the interoperability crossing these two networks becomes increasingly important for modern communications. A transcoding system that translates the coding parameters directly between the GSM and G.729 speech coders is discussed in the present paper. The GSM coder is used for mobile communications while the G.729 is the most favorable speech coder in Internet communications. For Internet/wireless gateway servers, it is evident that the proposed transcoding system requires much less computation than the conventional decode-then-encode (DTE) approach.
