A distributed scheme for integrated predictive dynamic channel and power allocation in cellular radio networks

We propose a distributed dynamic channel and power allocation (DCPA) scheme based on a novel predictive power control algorithm. The minimum interference dynamic channel assignment algorithm is employed, while simple Kalman filters are designed to provide the predicted measurements of both the channel gains and the interference levels, which are then used to update the power levels. Extensive computer simulations are carried out to show the improvement in performance, under the dynamics of user arrivals and departures and user mobility. It is shown that the number of dropped calls and the number of blocked calls are decreased while, on average, fewer channel reassignments per call are required.
