- Abstract
- Abstract--In this paper, a frequency- and time-division multiple-
access (F-TDMA)-based mobile radio system using both
dynamic channel allocation (DCA) and frequency hopping (FH)
is investigated. We propose a new interference adaptive DCA
(IA-DCA) algorithm that is suitably designed for a network implementing
FH. The role played by the power control algorithm in
this DCA-FH context is also investigated. We compare the performance
of our proposal to that of fixed channel allocation (FCA)
with and without FH and the well-known IA-DCA schemes investigated
in the literature in the absence of FH. The performance
results show that interesting synergic effects can be obtained in
terms of forced termination and user satisfaction probability by
using both DCA and FH. The results we show in the paper have
been achieved by means of a system-level simulation tool which
takes propagation, user mobility, interference, traffic, and channel
allocation into account. The advantages of using FH are accounted
for by using a suitable analytical model that gives the frame error
rate as a function of the carrier-to-interference ratio and the
number of hopping frequencies, at link level; this model is taken
from the literature where it was presented for FCA, and here it is
modified in order to be applicable to the DCA case. (literal)
