This paper presents simple closed-form expressions for the ergodic channel capacity of SIMO (single-input and multiple output) wireless systems operating in a Nakagami fading channel. As the performance of SIMO channel is closely related to the diver... Read More about Simple Closed-Form Channel Capacity Formulas for the SIMO Nakagami Channel.

In frequency-nonselective fading channels, the partial waves arriving at the mobile receiver cannot explicitly be of homogeneous nature due to nonuniform scattering caused by objects of specific reflective nature. Moreover, shadowing influences the r... Read More about The Weibull–Lognormal Fading Channel: Analysis, Simulation, and Validation.

This paper presents a mixture stochastic process by multiplying a Weibull process with a lognormal one. The first one models the possible scattering non-uniformities of the channel, whereas the second accounts for the slow term variations of the loca...

A Small Scale Fading Model with Sectored and Three Dimensional Diffuse Scattering (2008)
Presentation / Conference Contribution

In frequency non-selective fading channels the multipath components can arrive at the mobile receiver via a three dimensional (3-D) scattering mechanism. That case occurs especially in urban environments, in which the tall buildings and other obstacl... Read More about A Small Scale Fading Model with Sectored and Three Dimensional Diffuse Scattering.
