Abstract

In this paper we consider the problem of efficiently serving multiple uplink video users in a wideband CDMA wireless communication system with mixed voice and video traffic. Very low available video bit rate (<64kpbs) and multi-user interference are the major limiting factors in the system performance. Our solution is based on video summarization to achieve reasonable video quality at very low bit rate, and multi-user transmission adaptation/scheduling via summarization distortion-rate profile negotiation between base station and mobiles to meet power control constraints and minimize the interference among voice/video users. The simulation results demonstrate the effectiveness of the proposed approach.
