摘要

The forward-link (base to mobile) power-control problem in code division multiple access (CDMA) cellular systems is studied. For a better understanding of the problem, a simple analytical model is developed for the neighboring-cell interference experienced by users as a function of distance from their home base station. Using this model, the recently proposed nth-power-of-distance power-control laws are investigated, especially with regard to the possibility of creation of a service hole. The investigation leads to the shape of the optimum radial distance dependent power-control law that will provide uniform service to all the users.
