Abstract :
A CDMA cellular scheme that dynamically adapts the cells to the spatial load distribution is proposed. The scheme maximizes the network capacity for a given number of base stations, for any distribution of the mobile users. It combines power control, base station assignment and adaptive sectorization efficiently, and can be easily integrated into the already deployed CDMA systems. Simulation results show that our relatively low complexity approach, achieves a performance quite close to that of an optimal beamforming scheme under uniform and non-uniform load scenarios
