Efficient cost function evaluation for WCDMA network optimization

The paper describes a very efficient method of WCDMA network analysis dedicated for its optimization. The method is based on a transformed form of the well known system of linear equations for the downlink. This approach allows computational complexity to be decreased even over 20 times compared to the conventional CDMA network analysis methods (i.e. based on the power control algorithm). Additional speedup can be achieved by proper and precise numerical implementation of the presented algorithm.
