Abstract

In this paper, a trellis-based prediction algorithm was applied for the power control of WCDMA system for the first time. The principle of the algorithm was described. The power control events were modeled by a sequence of 0s and 1s by devising a trellis-based prediction method that adjusted the transmitting power strength based on the similarity of the power control states. The system capacity is increased and the simulation time is saved by using the algorithm. Numerical results indicate that the performance of the trellis-based prediction algorithm exceed that of conventional ones.
