Abstract

In WCDMA 3rd Generation (3G) systems although there is no need for frequency planning as the case with second generation (2G) systems, the limitation of both capacity and coverage by the interference level in the system rendered the planning task for 3G systems far more complex than 2G systems. As the 3G radio networks now more sensitive to radio environment and traffic conditions, the advantage of dropping frequency planning could be cumbersome due to difficulties linked to what is called Cell-Breathing Phenomenon (CBP). In this work we propose a Dynamic WCDMA system that adjusts the spreading factor adaptively to overcome this problem. The simulation design will have the output of mapping the network load in terms of the number of users to the E b/N0 required; this will give the network controller an idea about the number and type of users that may cause coverage to shrink i.e. start cell breathing. Therefore the network controller will be able to decide on the number and type of users admitted to the network at specific times.
