MPEG Transmission Enabled in High Speed Downlink Packet Access

Universal Mobile Telecommunications system (UMTS) is a third generation mobile communication system that supports variety of traffic such as voice only, mixed voice and data, streaming video, web requests email etc. Downlink data rates up further increased by the enhanced UMTS known as High Speed Downlink packet Access (HSDPA). Real time streaming video is becoming very popular because of the wide variety of applications it can support, Video applications produce large amount of data as a result they are transmitted in compressed format. This work investigates the performance of streaming MPEG-4 video over the HSDPA channels with varying channel conditions. In particular the performance of HS-DSCH channel for real time video transmission is examined. Simulation results show that Radio Link Protocol (RLC) operating in acknowledges (AM) mode outperforms the unacknowledged mode (UM). UM mode provides timely delivery.
