A Tractable Product Channel Model for Line-of-Sight Scenarios. (arXiv:1711.05650v1 [cs.IT])
来源于:arXiv
We here present a general and tractable model for line-of-sight (LOS)
scenarios, which is based on the product of two independent and non-identically
distributed $\kappa$-$\mu$ shadowed random variables. Simple closed-form
expressions for the probability density function, cumulative distribution
function and moment-generating function are derived, which are as tractable as
the corresponding expressions derived from a product of Nakagami-$m$ random
variables. This model simplifies the challenging characterization of LOS
product channels, as well as combinations of LOS with non-LOS ones. It also
shows a higher flexibility when fitting measurements with respect to exact
approaches based on the Rician distribution. 查看全文>>
