Link Adaptation and Power Control for Streaming Services in EGPRS Wireless Networks

Overview Using the MPEG-4 Advanced Audio Coder (AAC) music as an example of streaming applications, the authors investigates the improvement of error performance for the streaming service by link-adaptation and power-control techniques in an Enhanced General Packet Radio Services (EGPRS) cellular network. A low packet error rate and variability are essential in providing short error-burst length so that error concealment techniques can be effectively applied to music packets. In this paper, the effects of a combined link adaptation and power control scheme (referred to as the error-based scheme) for achieving a target error rate and reducing error variability is studied.
