Abstract :
A sparse Multiple-input Multiple-output (MIMO) channel model in high-speed railway scenario is obtained in this paper using the Virtual Channel Representation (VCR). The MIMO time-variant channel is investigated in receive, transmit antenna and Doppler domains. And the sparse channel analysis algorithm is combined with the Higher-Order Singular Value Decomposition (HOSVD) to study the spatial characteristics of H(t).
