FGa power control for DS/CDMA reverse link cellular system

This paper introduces the application of FGa (fuzzy logic and genetic algorithm) to control the power of DS/CDMA cellular system in the reverse link over the fading channels. The conventional algorithm, fixed-step power control, is suffered from poor system stability. To solve this problem, a fuzzy control is used for determine the user's transmitting power in order to maintain the power received at the base station nearly equal. Genetic algorithm is applied into fuzzy logic controller for generating fuzzy rule-base, the shape and range of each membership function to achieve the optimization controller.
