“…This is due to the fact that spatial diversity in reality includes both horizontal and vertical parts, while the 2D model ignores the vertical part which leads to an overestimation in the spatial CCF. This agrees with the conclusion reported in [20] …”

Abstract-This paper proposes a novel three-dimensional (3D) cylinder geometry-based stochastic model (GBSM) for nonisotropic multiple-input multiple-output (MIMO) Rice fading channels in high-speed train (HST) wireless communications under deep cutting scenarios. Using a validated approximation, the closed-form expression of the space-time correlation function (ST CF) of the proposed GBSM is obtained. Different from twodimensional (2D) channel models, in the 3D GBSM the elevation angles and the height of the base station (BS) antenna relative to the mobile station (MS) one are introduced.The numerical results show the rationality of the approximation and how the arrangements of antennas affect the ST CF.

“…However in realistic propagation environments, the promised theoretical gains are not realized due to the significant spatial correlation present in the MIMO channels. Our observations in [5] show that the 2D model clearly overestimates the correlation, which is a consequence of ignoring the directivity of antennas and the propagation of multi-paths in the elevation. Assuming the radiation of energy from all the antennas to be in the same fixed direction in the elevation will cause the antennas to appear more correlated [6].Therefore exploiting the channel's degrees of freedom in the elevation can further enhance the system performance by benefiting from the richness of real channel which consequently results in lower MIMO spatial correlation.…”

“…Our 3D channel modelling implementation considers both propagation in the azimuth and elevation plane based on pointto-point predictions from each AP to every UE location for each site-specific urban databases, which results in a more accurate estimation of channel capacity, spatial correlation and system level performance as shown in our previous work in [5]. An isotropic antenna was deployed in the stage of channel generation in order to provide a generic channel model with no impact from the antenna system.…”

“…Exploiting the 3D spatial dimensions (azimuth and elevation) of MIMO channels is critical in improving the spectral efficiency and the reliability of the radio link. The assumption of 2D modelling results in inaccurate estimation of system level performance and ergodic capacity as discussed in [4] [5], especially in environments where the assumption of 2D propagation breaks downs because the elevation spread is significant.…”

Abstract. WiMAX is a promising technology for a higher spectral efficiency and reliable transmission. This paper compares the downlink throughput experienced by mobile users in a macro-cell in an interference limited scenario with a frequency reuse of one. Bit accurate link level simulations are performed for the downlink physical shared channel (PDSCH). The study is performed for a single antenna system in specific routes at two different carrier frequencies (800 MHz and 2.6 GHz), for two urban environments in the China, and two cell sizes. The paper also considers the carrier aggregation technique which has been proposed since it is difficult to ensure a single wide frequency band for operators. A state-of-the-art 3D ray tracer tool is used to generate 3D channel models for accurate modelling of channel statistics. The study shows that the 800 MHz band has no greater effect on the downlink throughput as compared to 2.6 GHz band, which leads to no additional advantages of inter-band aggregation (considering 800 MHz) compared to intra-band aggregation. It is also observed that a range of speeds can be handled while maintaining good performance in WiMAX. We have clearly shown that the choice of cell size by mobile operators for optimum coverage depends mainly on the propagation characteristic of the environment.
