Forward link unbalancing power control based on channel modulation scheme for wireless multimedia CDMA systems

This paper proposes a forward link unbalancing power control algorithm which is based on a channel modulation scheme for wireless multimedia CDMA mobile systems. The forward channel adopts dual orthogonal spreading codes and a multicode modulation scheme to meet different data rate traffic requirements. The proposed power control algorithm is the integration of a priority scheme and forward link power allocation and adjustment. The numerical results show that the unbalancing power control can guarantee the QoS requirements of traffic with higher priority even for the condition of heavy traffic.
