Min-max model predictive power control strategy for CDMA cellular networks

This paper applies an open-loop min-max MPC strategy to the uplink radio power control problem for a CDMA cellular network assessed over time-varying channels. The new power control algorithm is shown to robustly compensate for channel fading uncertainty as well as to reduce the effect of interference. This is achieved by implementing a computationally efficient min-max MPC mechanism based on a simple model of the tracking error that is estimated at each sampling time from the local SINR. The numerical efficiency of the resulting design is benchmarked against a number of existing strategies via a representative selection of simulation scenarios.
