TRANSMISSION OF VIDEO IN WIRELESS ENVIRONMENT

Abstract

A cross-layer adaptation scheme, which can be applied in a femto base station, is proposed for quality of service provisions for the scalable video streaming of high definition content in a wireless environment. Within the procedure of minimum video distortion optimization framework, the method can dynamically adopt the cross-layer parameters, which contain the video rate, payload length of a packet, the mode of modulation and coding scheme. Based on channel quality and related parameters, the proposed scheme formulates the problem of parameter selection into an optimization problem, which can be automatically solved.
