Robust Power Controllers in Cellular Radio Systems
Huan Zhang, Pubudu Nishantha Pathirana, Samitha W. Ekanayake · 2008
The paper presents a framework to design robust transmit power controllers in cellular radio systems. The robust controllers designed are able to guarantee the quality of service (QoS) by keeping the carrier-to-inference-plus-noise ratio (CIRN) above a desired level in face of network link gain variations. The controller design problem is solved by solving a noncooperative dynamic game between the controller and unknown link gain variations.
