Abstract :
The design of binary power control algorithms for cellular communication systems is considered in context of code division multiple access (CDMA). The control problem is posed as a tradeoff between the desire for users to meet their signal-to-interference ratio (SIR) requirements and the need to minimize the transmitted signal energy over the duration of their calls. The dynamic nature of the wireless channel for mobile users is incorporated in the problem definition. Based on dynamic programming arguments, an optimal single-user solution is obtained
