%X An out loop power control algorithm based on continuous fuzzy control is presented in this paper. The variation value of the block error rate is processed by fuzzy control, and the output value which is obtained by fuzzy control rules and defuzzification is adopted as the step size to adjust the SIR target of the inner loop power control. The algorithm can acquire the best adjusting step accurately, thus it avoids the overshoot phenomenon of the existing outer power control methods. In addition, with the variation of the network and the wireless environment, the average BLER can fast converge at the required BLER target value which meets the quality of the services. The experimental results validate the excellent properties of the algorithm.
