“…More precisely, in this study, the Directive model was used to assess the contribution of the DS. This choice was motivated by the fact that, when compared to the other DS models used in literature (i.e., Lambertian model), Vittorio degli Espositi et al, [33] demonstrated that the Directive model best follows the experimental measurement (also demonstrated by [34]). Specifically, the DS was applied to the building walls; as parameters were set the scattering factor "S" = 0.45, the crosspolarization fraction "K-pol" = 0.4, and the alpha value, i.e., the amplitude of the lobe scatterer ray, as 4 [33]- [36].…”

In recent years wireless propagation channel research has paid considerable attention to dense multipath, which is an indispensable part of propagation channels and may significantly contribute to the received power in variety of environments and frequency bands. Mathematical representation of dense multipath is different from that of specular components (SCs) due to its distinct propagation mechanism and impact on system performance. Therefore, accurate understanding and modeling of dense multipath together with SCs are important for parametric channel estimation and for reliable simulation in wireless applications. This paper first presents a systematic survey of studies of dense multipath in terms of different representations, channel modeling approaches and estimation methods. Thereafter, a comprehensive review of the characteristics and impact of dense multipath on performance of communication, localization and sensing systems is provided. Finally, open research topics are discussed.INDEX TERMS Channel estimation, channel modeling, characteristics, communication, dense multipath.

“…In general, as the frequency increases, surfaces appear rougher and lead to more diffuse scatterings [4], there is higher path loss, and higher sensitivity to line-of-sight (LOS) blockage. For non-LOS (NLOS) mmWave propagation, especially for vehicle-to-everything communications in urban scenarios [5], specular components together with single-bounce diffuse components form a majority of the overall channel gain [4]. Diffuse multipath is often treated as a disturbance, though geometry-based diffuse scattering channel models can also be considered, where each surface contributes with a cluster of paths, all with similar angles and delays [6], [7].…”

5G mmWave communication systems have the potential to jointly estimate the positions of user equipment (UE) and mapping their propagation environments using a single base station. But such potential depends on the characteristics of the reflecting surfaces, such as a deterministic specular nature, a stochastic diffuse/scattering nature, or a combination of both. In this letter, we proposed a 5G positioning and mapping algorithm with unknown orientation and clock bias for single-bounce diffuse multipath channel models. The method is able to accurately localize, calibrate and synchronize the UE, even in the absence of line-of-sight and specular components. This enables robust positioning and mapping using only diffuse multipath.
