Statistical Properties and Channel Capacity of the 3D Massive MIMO GBSM
In order to evaluate the performance of the 3D GBSM in tunnels more effectively and associate the effective scatterers in the propagation environment with the multiple antennas' performance, the statistical properties, such as STCF and PDFs, and the capacity need to be analyzed.
In this paper, we have proposed a novel GBSM for small-scale non-WSSUS V2V double-Rayleigh fading channels.
This is a salient feature of our proposal, because to the best of our knowledge, the GBSMs for V2V channels that have been proposed under similar considerations (i.e., by assuming a double interaction with IOs and the propagation of plane waves) do not take into account the temporal dynamics of the propagation delays (see, e.g., [24-26]).
However, to the best of the authors' knowledge, the GBSMs that have been proposed for doubly and triply selective V2V channels assuming the propagation of plane waves and a double interaction with IOs fulfill the WSSUS condition by design [24-26].
The data from GBSM on optimum refinery sites and spatial land use change, and bioconversion data from Aspen Plus, were used in SimaPro v.7.3.3 (PRé Consultants 2012) to assess environmental impacts of poplar production.
We used GBSM to assess the economic efficiency of potential poplar-based jet fuel facilities in Northern California each with a production capacity of 100 million gallons per year (MGY).
Rather than trying to measure the MIMO channel or merely deducing the theoretical MIMO model, this study is based on the combination of SISO channel measurement results and the GBSM. Temporal fading characteristics involving K-factor and Doppler power spectral density (PSD) are derived from channel measurements in an obstructed viaduct scenario on Zhengzhou-Xi'an HSR in China.
In this section, according to the combination of the temporal fading results and a theoretical GBSM, we establish a semiempirical MIMO channel model for the measured HSR viaduct scenario.
In consideration of both the nonstationary phenomenon and spherical waveform effect, an elliptical GBSM was given for massive MIMO with linear antenna array [23, 32, 33].
