A Three-Dimensional Geometrical Scattering Model for Cellular Communication Environment

Comments on “A Three-Dimensional Geometrical Scattering Model for Cellular Communication Environment”

“…A three dimensional (3D) geometric channel model proposed in [1] is a simplified case of models presented in [2][3][4]. In previous models proposed by , we may notice an increase in their complexity.…”

“…In previous models proposed by , we may notice an increase in their complexity. In contrast, the newest model presented in [1] is a trivial simplification of these models. Although, the models in [2][3][4] concern a mobile-tomobile (M2M) scenario, while the models in [1] is dedicated to a fixed-to-mobile (F2M) scenario.…”

“…In [1], numerous errors in the description, introduced symbols, and equations occur there. Hence, the obtained results are erroneous and make it impossible to correctly interpret a propagation phenomenon occurring in a real environment.…”

“…Hence, the obtained results are erroneous and make it impossible to correctly interpret a propagation phenomenon occurring in a real environment. A detailed analysis of the models in [1] and [2][3][4] shows that most of the formulas presented in [1] are simplified versions of equivalents of the previous works. However, the transformation of the models from [2][3][4] is carried out negligently.…”

“…However, the transformation of the models from [2][3][4] is carried out negligently. Hence, many of the symbols used in [1] do not have their counterparts in the analyzed solution. As a result, the presented formulas contain the fundamental errors that undermine the credibility of this paper.…”
