This chapter studies a composite stochastic model, in which the diffuse component arises from three dimensional (3-D) multipath scattering. That case occurs especially in dense scattering environments, in which the tall obstacles cause arrival of mul...

Το αντικείμενο της παρούσης διατριβής είναι η μοντελοποίηση με χρήση στοχαστικών διαδικασιών, ασυρμάτων μη επιλεκτικών στη συχνότητα καναλιών με διαλείψεις (frequency non-selective fading channels). Η γνώση και μοντελοποίηση των χρονικών μεταβολών τω...

This paper presents 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 diversity c... Read More about Ergodic Capacity for the SIMO Nakagami- Channel.

A Modified Loo Model with Partially Blocked and Three Dimensional Multipath Scattering: Analysis, Simulation and Validation (2009)
Journal Article

This paper presents a novel mobile fading channel model, belonging to the class of Loo models, in which the multipath power arrives both in three dimensions (3-D) and in two angular sectors at the azimuth receiver’s plane. Moreover shadowing affects... Read More about A Modified Loo Model with Partially Blocked and Three Dimensional Multipath Scattering: Analysis, Simulation and Validation.
