A semiempirical multiple-input multiple-output (MIMO) channel model is proposed for high-speed railway (HSR) viaduct scenarios. The MIMO based on the combination of realistic single-input single-output (SISO) measurement results and a theoretical geometry-based stochastic (GBSM). Temporal fading characteristics involving<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>K</mml:mi></mml:mrow></mml:math>-factor Doppler power spectral density (PSD) are derived from wideband under an obstructed Zhengzhou-Xi’an HSR in China. GBSM composed one-ring elliptical employed to describe entire propagation environment. Environment-related parameters determined by measured temporal properties. And close agreement achieved between data. Finally, deterministic simulation established perform analysis space-time correlation function, space-Doppler PSD, capacity scenario. This more particularly beneficial performance evaluation systems environments.
