Popis:	This article deals with mathematical modeling of UMTS network. The presented model is designed for interference analysis in this network. The paper presents the set of simulations based on an idea of a specific order of Walsh codes. In the first part the mathematical model is presented. This model is designed for Matlab and is based on 3GPP specifications. The second part describes the method of specific ordering of Walsh spreading codes. The specific order can decrease the interference level in the radio network of UMTS which is caused by multipath propagation. The simulation results are presented, too.
