Abstract :
Resource allocation in a frequency hopping network is even more problematic than in a traditional network. The combined effect from all serving frequencies has to be considered directly in the allocation process. An algorithm doing this for a PCS1900/GSM/DCS1800 type of network is presented. The frequency as well as the interference diversity gain from frequency hopping is included directly in the allocation process. Exploiting a cost function, which includes the gain from frequency hopping, a performance enhancement of around 20% is achieved compared to an operating reference frequency plan. A graphical visualisation tool has been developed as well. This tool uses a network quality measure tightly linked to the FER rather than the traditional C/I or BER. Using these statistics an increase in network quality is shown
