Scalable Video Transmission over Multirate GMC-CDMA Wireless Channels

Abstract

We consider the problem of video transmission over wireless generalized multicarrier code division multiple access (GMC-CDMA) systems. Such systems offer deterministic elimination of multiple access interference (MAI). A scalable video source codec is used and a multirate setup is assumed, i.e., each video user is allowed to occupy more than one GMC-CDMA channel. Furthermore, each of these channels can utilize a different number of subcarriers. We solve an optimization problem to determine the source coding and channel coding rates for the user of interest, as well as the number of subcarriers for each GMC-CDMA channel. Experimental results are presented and conclusions are drawn.
