Transmission design and QoS oriented resource management based on integrated internet and DVB-T network

Abstract

Digital Terrestrial Video Broadcasting (DVB-T) provides an ideal means for providing services with both high data rate and high mobility, which exceeds the ability of current existing access technologies like UMTS, WLAN, and so forth. Combined with other media for the uplink as a return channel for user requests and acknowledgement signaling, DVB-T can supply interactive data services. In this paper, we show the architecture of integrated Internet and DVB-T network to provide interactive broadband Internet access services for users with high mobility. In order to fully exploit the valuable broadcast resources and provide services with effective QoS differentiation, we present a bandwidth allocation algorithm SOBAM(Satisfaction Oriented Bandwidth Allocation Method) based on a new concept: user satisfaction. Simulation results prove the good performance of SOBAM, and show that with SOBAM, the integrated Internet and DVB-T network can provide a soft system capacity which is similar to the one in CDMA networks. 1 1164 0-7803-9152-7/05/$20.00
