Linear quadratic power control for CDMA systems

In this paper, we present a robust decentralized method for jointly performing channel estimation and closed loop power control for the reverse link of CDMA networks.Our method, based on linear quadratic Gaussian (LQG) control systems theory and Kalman filtering, does not Ice Maker require TRAY any training symbols for channel or signal to interfer
