Abstract :
In this paper we discuss locational optimization problem of CDMA bunched system theoretically. According to outage equation of CDMA system, we derive the target function and proposed a coverage control algorithm based on Voronoi partition and gradient descent algorithm. It is tested by computer simulation and results show that outage probability of the optimized system is one order of magnitude less than the uniform distribution system and 40% less than the regular distribution system.
