| Summary: | Multipaths represent a common predominant and
uncontrolled component on channel impairments for all terrestrial
and Land Mobile Satellite systems. Without restrictions w.r.t mobile terrestrial applications, the addressed multipath problematic
in this paper is focused on Land Mobile Satellite applications
where delayed signal replicas are highly impacting performances
on communication systems while they induce strong positioning
errors for navigation systems. The actual trend in propagation
channel modelling is to improve the multipath characterisation
and representation by using semideterministic and hybrid
physical-statistical models into channel simulators instead of
narrow-band empirical approaches. In this context, this paper
presents a new simplified model, called 3CM (3-Component Model) to reproduce building scattering in an efficient way
which strongly improves computation performances. This model
is based on asymptotic methods, namely, PO (Physical Optics)
which allows the 3CM to be frequency scalable, polarimetric, and
dielectric materials oriented. Note that the proposed model and
the retained approach can be integrated into more complex tools
such as existing ray tracers. However, this issue is not discussed
in this paper. |
