Performance Evaluation of MPEG-4 Video Transport in Rayleigh Fading Channel

In this paper, we present a new analysis of the optimal throughput of a single user for transporting MPEG-4 video over Universal Mobile Telecommunication System (UNITS) network. A wireless channel considers that bit errors associated with link-layer packets are due to the time-varying features of a Wideband Code-Division-Multiple Access (WCDMA) channel. By this network, the perceived video quality can be evaluated based on the heuristic function of TCP throughput which is dependent of the user's mobility (Doppler frequency) over a Rayleigh fading channel. The results show that a video quality of service (QoS) in terms of temporal scaling can be significantly adapted at fast fading region when the maximum network throughput of acknowledged mode is achieved under optimal packet length in radio-link layer.
