Abstract

In this paper we have proposed a new distributed power control algorithm based on Kalman filter. Our motivation to use Kalman filter is the known fact that the Kalman filter is the optimum linear tracking device on the basis of second order statistics. We have presented the power control problem in state space representation. The Kalman algorithm has been applied to estimate the optimum transmitted power. Our main objective is to make the actual QoS track some predefined target QoS. The QoS is defined as the CIR in the communication system. The simulations show the effectiveness of our algorithm.
