Variable rate speech coding and network delay analysis for universal transport network

An exploration is made of some techniques which will play important roles in the development of the future universal transport network. In the network, the information can be efficiently integrated and transported by making the most of the burstiness of the information flows and of the store-and-forward process at the transport nodes. First, a coding and multiplexing scheme for audio signals matched to the above transportation mode is proposed. The effectiveness of the scheme is demonstrated through computer simulation and the extent of the deviations are provided for some sets of parameters. The analysis provides useful tools to perform sensitivity analysis of network delay performance
