Performance of a dynamic channel allocation scheme with frequency hopping, power control and handover in a mobile radio system

An F-TDMA (frequency and time division multiple access) based mobile radio system using both dynamic channel allocation (DCA) and frequency hopping (FH) is investigated in this work. This paper follows the work of Verdone, Zanella and Zuliani (see IEEE PIMRC'01, San Diego, CA, September 2001), where the same authors proposed a new interference adaptive DCA algorithm that is suitably designed for a network implementing FH. The role played jointly by the power control and handover algorithm in this mixed DCA-FH context is investigated in this paper. We compare the performance of our proposal to that of fixed channel allocation with FH. The performance results show that interesting synergic effects can be obtained in terms of user satisfaction probability by using both DCA and FH. The results we show in the paper have been achieved by means of an integrated approach taking both system level and link level aspects into account.
