Mobile Positioning in MIMO System Using Particle Filtering

In English Abstract—This paper represents the results of a
simulation study on positioning of a mobile unit in
MIMO settings. We used two different approaches
for modeling the mobile movement, combined with
a simple geometrical model for the MIMO channel.
Three different particle filters were implemented for
the position estimation. The results show that all three
filters are able to achieve estimation accuracy required
by Federal Communication Commission. The dimensionality
of the particle filter state space is independent
of the number of antenna elements, and it is possible to
increase the number of antennas and use more sophisticated
channel models without changing the filtering
algorithms.
