“…There are scarcity of measured channels with respect to both delay statistics and the Doppler statistics in tunnel environments. Therefore, we use only the delay spread of the measured channel reported in [36]. Thus, we have set the weighting factor W 1 to zero, implying that the error function E min in (67) equals E min = E 2 .…”

“…There, it has been shown that the channel statistics of the WINNER-based model are close to the deterministic one, which are obtained from a 3D ray tracing simulator. In [36], the authors measured a channel inside an arched tunnel and analyzed the radio propagation channel in terms of delay spread and dominant scatterers. The investigations showed that more than 90% of the extracted paths consist of LOS and single-bounce scattering components.…”

Abstract-In this paper, we present a wideband multiple-input multiple-output (MIMO) car-to-car (C2C) channel model based on a geometrical semicircular tunnel (SCT) scattering model. From the geometrical SCT scattering model, a reference channel model is derived under the assumption of single-bounce scattering in line-of-sight (LOS) and non-LOS (NLOS) propagation environments. In the proposed reference channel model, it is assumed that an infinite number of scatterers are randomly distributed on the tunnel wall. Starting from the geometrical scattering model, the time-variant transfer function (TVTF) is derived and its correlation properties in time, frequency, and space are studied. Expressions are presented for the spacetime-frequency cross-correlation function (STF-CCF), the twodimensional (2D) space CCF, the 2D time-frequency CCF (TF-CCF), the temporal autocorrelation function (ACF), and the frequency correlation function (FCF). Owing to the semicircular geometry, we reduced the originally threefold integrals to double integrals in the computations of the correlation functions, which simplifies the numerical analysis considerably. From the TVTF characterizing the reference model, an efficient sum-of-cisoids (SOC) channel simulator is derived. Numerical results show that both the temporal ACF and the FCF of the SOC channel simulator match very well with those of the reference model. A validation of the proposed model has been done by fitting the delay spread of the reference model to that of the measured channel, which demonstrates an excellent agreement. The proposed channel simulator allows us to evaluate the performance of C2C communication systems in tunnel environments.

“…Other studies, published in the literature, deal with pedestrian tunnels (Molina-Garcia-Pardo et al, 2003 where the position of the outside antenna is critical for the performance of the system.

Abstract-The delay caused by the reflected ray in broadband communication has a great influence on the communications in subway tunnel. This paper presents measurements taken in subway tunnels at 2.4 GHz, with 5 MHz bandwidth. According to propagation characteristics of tunnel, the measurements were carried out with a frequency domain channel sounding technique, in three typical scenarios: line of sight (LOS), Nonline-of-sight (NLOS) and far line of sight (FLOS), which lead to different delay distributions. Firstly IFFT was chosen to get channel impulse response (CIR) h(t) from measured threedimensional transfer functions. Power delay profile (PDP) was investigated to give an overview of broadband channel model. Thereafter, a long delay caused by the obturation of tunnel is observed and investigated in all the scenarios. The measurements show that the reflection can be greatly remained by the tunnel, which leads to long delay cluster where the reflection, but direct ray, makes the main contribution for radio wave propagation. Four important parameters: distribution of whole PDP power, first peak arriving time, reflection cluster duration and PDP power distribution of reflection cluster were studied to give a detailed description of long delay characteristic in tunnel. This can be used to ensure high capacity communication in tunnels.
