“…K xpol usually ranges between 0 and 0.2 in outdoor environment [ Vitucci et al , ], where therefore the polarization of the incident wave tends to be preserved. On the contrary, values of K xpol close to 0.5 are achieved in typical office and laboratory environments [ Mani et al , ], meaning that the diffuse scattering component tends to be completely depolarized in complex indoor scenarios.…”

Applied for the first time to mobile radio propagation modeling at the beginning of the nineties, ray tracing is now living a second youth. It is probably the best model to assist in the design and planning of future short-range, millimeter-wave wireless systems, where the more limited propagation environment with respect to UHF frequencies allows to overcome traditional high-CPU time limitations while the higher operating frequency makes ray-optics approximations less drastic and allows to achieve an unprecedented level of accuracy. An overview of ray tracing propagation modeling is given in this paper, with a special attention to future prospects and applications. In particular, frontiers of ray-based propagation modeling such as extension to diffuse scattering, multidimensional channel characterization, multiple-input multiple-output (MIMO) capacity assessments, and future applications such as real-time ray tracing are addressed in the paper with reference to the work recently carried out at the University of Bologna.

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.

“…However, for some scenarios, for example, in the indoor environment, clutter is not the most challenging due to the stationary background, which can be solved by background cancelation [7], but dense multipath severely decreases the detection performance [8,9]. The authors in [10,11] studied the multipath scattering in the indoor scenario and showed that multipath is related to polarisation, including elevation angle-of-arrival and signal power. For different elevation angles, the cross-polarised signals have similar power levels while the power of co-polarised multipath signals is quite different from each other [12].…”

Polarisation diversity radar enhances the performance of target detection. Time reversal exploits the multipath effect by adaptively matching propagation channels to improve the signal-to-noise ratio (SNR) and realise high detectability. This work combines polarisation diversity and time-reversal technology to propose a time-reversal detector suitable for a polarisation array radar. The maximum likelihood estimate is carried out for the timevarying channel response to solve the channel mismatch problem, which may cause the degradation of time-reversal performance. In addition, a conventional polarisation detector is developed under the same varying channel scenario to benchmark the timereversal detector, and furthermore, the SNR gain of the time-reversal detector over the conventional detector is derived. Numerical simulations demonstrate the superiority of the time-reversal detector. Both the polarisation detectors proposed can take advantage of the channel variations to improve the detectability, and the greater the energy brought by the channel changes, the better the detection performance achieved.
