Abstract :
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.
