Abstract-In this letter, spatial channel characterization in highspeed railway (HSR) scenarios is investigated using a moving virtual array measurement approach. Based on the wideband single-antenna measurements conducted on high-speed railway (HSR) in China and the moving virtual array measurement scheme, 1 × 3 single-input-multiple-output channel impulse responses are generated. Spatial characteristics in the obstructed viaduct and deep cutting scenarios, focusing on angle of arrival, angle spread, and spatial correlation, are analyzed. The obtained results can fulfill the gap of HSR spatial channel models and provide helpful reference for the assessment of HSR multiantenna technologies. Index Terms-Angle of arrival (AoA), angle spread (AS), highspeed railway (HSR) channel, spatial correlation (SC), virtual array.
In REF , spatial characteristics, involving angle of arrival (AOA), root-mean-square (RMS) angle spread (AS), and spatial correlation (SC), were analyzed according to a socalled moving virtual antenna array (VAA) scheme.
