This article introduces the FORMAT array, a reconfigurable millimeter-wave antenna array platform based on tiles. stands for Flexible Organization and Reconfiguration of Millimeter-wave Antenna Tiles, which is unique hardware solution aiming to implement demonstrate variety concepts, as well different architectures configurations from same basic module, providing even benchmark between solutions thus valuable insights into fifth-generation (5G) beyond-5G systems. The combination...
The use of millimeter-wave (mm-wave) frequency bands for fifth-generation (5G) cellular mobile communications has led to intense interest from academia and industry over these spectrum resources. Despite extensive measurement campaigns channel modeling efforts, there is a lack deterministic backscattering models addressing the impact size orientation static scatterers on radio channel. In this article, two 3-D computationally efficient calculating based Fresnel integrals error function are...
Backscattering is an essential phenomenon in millimeter-wave (mm-wave) propagation.Accordingly, computationally efficient models characterizing this process are now available the literature.However, these restricted to single-surface contributions.In paper, we propose a multiple-scattering model for calculating backscattered fields due consecutive interactions with several rectangular surfaces.In addition, later extended capture single-scattering blockage between backscattering events.The...
In this paper, we study the effect of element separation in a base station array (BSA) on downlink line-of-sight achievable sum-rate MIMO systems presence mutual coupling at BSA. The channel matrix H is modeled using embedded field patterns BSA and used to analyze outage performance for two single-element user equipments assuming no inter-user coupling.
Blockage and backscattering by objects are relevant phenomena in millimeter-wave propagation. Conventionally, these treated means of separate models and, turn, included the total channel response. In this letter, we propose a combined model for calculating both blocked backscattered fields from planar smooth electrically-large rectangular surfaces. The contributions letter twofold: first, single formulation fields; second, proposed blockage as well. Furthermore, can be implemented using...

Geometry-based stochastic channel models (GSCMs) are suitable at millimeter-wave (mm-wave) frequencies. Proper forward-scattering and back-scattering modeling is needed in order to realize realistic assessments. In this paper, a recently-proposed model, 3D Fresnel, goes through further investigations: first, we investigate the impact of frequency results single scenario and, second, study effect multiple surfaces. both cases, model shows good agreement with respect Physical Optics (PO)...
