Abstract

We study the problem of how to efficiently distribute network resources among H.263 packet video streams in a multi-code CDMA network. Due to high flexibility of both the video encoding system and CDMA system, it is not trivial to find an optimal solution for the problem. We present different algorithms for transferring video in CDMA networks. We compare those algorithms in our simulation environment with multiple video users at different situations and show the results with various system loads. By observing those results, we come to a conclusion and come up with some guidelines for design code assignment algorithm for video traffic in wireless networks.
