Abstract

Power control is the most important system requirement for wireless cellular communication systems. In this paper, robust adaptive power control is considered for wireless cellular communication systems with nonlinear disturbances due to communication channel noises. Modified least-squares scheme with a relative dead zone is developed to work with the control law to form a novel robust adaptive control algorithm, without much prior knowledge of the system. The simulation results show that the proposed algorithm has good performance.
