Total frequency hopping for home base stations

This paper addresses the problem of allocating frequencies in a GSM-based home base station (HBS) system. A novel solution called total frequency hopping (TFH) is presented in order to overcome the frequency allocation and the inter-HBS synchronisation problems. The HBS system will use the same frequency band as the overlaying GSM network and thus result in more interference. The simulation results reveal that the negative impact of the underlying HBS system to the GSM network performance is minimal.
