Abstract
cdma2000 EV-DO service was deployed in Korea in 2004. Even though it provides a bandwidth up to almost 2 Mbps, channel quality is time-varying so that service quality should be controlled adaptively. This paper discusses the measurement and analysis of the EV-DO channel quality. Based on the analysis, it proposes a proxy node that is located in the base station, informs the corresponding node of current channel quality. And information from the lower layer is also useful because it can be used to adapt the channel state more quickly and accurately . The proposed feedback control can be used well with scalable video coding.
