Mobile Radio Channel State Prediction for Power Control in WCDMA Mobile Network

Abstract

The mobile radio channel state prediction may be regarded as powerful tool to increase effects of loop power control in mobile radio network based on WCDMA, where the active fast power control is essential. Requirements on the appropriate prediction methods and obtained samples preprocessing include not only accuracy of prediction and low complexity of prediction model (what means easier implementation), but low delays and good modeling properties as well. This article deals with direct prediction of complex channel taps and power prediction by using adaptive and non-adaptive FIR predictor, and drafts the idea of implementation of predictor to the basic power control algorithm.
