Since CDMA is a kind of power-constrained or<br \/>\ninterference-limited system, its system capacity is not so ``hard'' as in bandwidth-limited<br \/>\nsystems, such as TDMA-based systems. In this paper, we analyze the uplink and downlink capacity of<br \/>\nmultimedia DS-CDMA systems based on constraint models. System capacity is given by \\emph{feasible<br \/>\ncondition}, which is the sufficient and necessary condition of the existence of feasible solutions<br \/>\nto the constraint model. As a byproduct, we also deduct the optimum solution to uplink and downlink<br \/>\ntransmit power minimization problem, which can be used as references for power control and radio<br \/>\nresource allocation multimedia DS-CDMA systems.<br \/>\n<span class=\"paper_subtitle\">KEYWORDS<\/span><br \/>\nDS-CDMA, capacity, constraint model, feasible condition.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"http:\/\/network.ee.tsinghua.edu.cn\/papers\/xiang_capacity_icc2003.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-117\" title=\"pdf\" src=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2010\/08\/pdf.gif\" alt=\"\" width=\"95\" height=\"50\" \/><\/a>Xiang Duan, Zhisheng Niu, Junli Zheng, <span class=\"papertitle\">Capacity Analysis of Uplink and Downlink in Multimedia DS-CDMA Systems Based On Constraint Models<\/span>, <span class=\"papersource\">Proc.
