Rj. Piechocki et al., A new stochastic spatio-temporal propagation model (SSTPM) for mobile communications with antenna arrays, IEEE COMMUN, 49(5), 2001, pp. 855-862
In order to evaluate the performance of third-generation mobile communicati
on systems, radio channel models are required. The models should be capable
of handling nonstationary scenarios with dynamic evolution of multipaths.
In this context and due to the introduction of advanced antenna systems to
exploit the spatial domain, a further expansion is needed in order to inclu
de the nonstationary characteristics of the channel. In an attempt to solve
these problems, this paper presents a new stochastic spatiotemporal propag
ation model. The model is a combination of the geometrically-based single r
eflection and the Gaussian wide-sense stationary uncorrelated scattering mo
dels, and is further enhanced in order to be able to handle nonstationary s
cenarios. The probability density functions of the number of the multipath
components, the scatterers' lifetime, and the angle of arrival are calculat
ed to support these features. The input parameters of the model are based o
n results from measurement campaigns published in the open literature.
