In another work, we provide a cross layer framework for the transmission of robust packet based H.264/AVC video over DS-CDMA wireless channels with near-ML multiuser detection using linear filters and reliability based processing. A cross layer framework is proposed for both underloaded and overloaded systems. In overloaded CDMA systems, when the number of users is greater than the processing gain, sub-optimal detection becomes more difficult because it is more difficult to separate the users because of the high correlation among the signatures. Such a scenario is of great interest because there are time that the processing gain cannot be increased due to bandwidth constraints.We next discuss the case where each scalable video layer is transmitted over a separate GMC-CDMA channel. In that case, we have Rs+c, i = B J i ... Our optimization problem now is as follows, for the case of T layers. For a given chip budgetanbsp;...
