| Summary |
We compare CDMA and FDMA (or TDMA) schemes
in multi-beam non-geostationary satellite systems,
taking the effects of antenna patterns on inter-cell interference into
consideration.
The maximum acceptable
number of users per cell in uplink is employed
as a measure of the system capacity.
We have found that
in FDMA (or TDMA) systems the maximum acceptable number of users
varies according to the altitude of the satellites,
while the performance is insensitive to the altitude in CDMA systems.
For this reason,
the altitude of the satellites is found to be an
important factor for selecting
multiple access schemes in non-geostationary satellite systems. |
