A new predictive algorithm for radio propagation model in WCDMA networks

In this paper, we present a novel algorithm to predict the coverage area of pilot channel, which can aid the RF optimization of WCDMA wireless networks. This algorithm exploits a radio propagation model without 3D digital map and inversion technique to reconstruct the median strength distribution of pilot signals in a cell with few measured data. Based on this distribution, we can determine the main coverage area of pilot channel. We show that our algorithm is accurate and fast enough to predict efficiently the coverage area which is one of the key tasks in the optimization process of WCDMA networks.
