Location-aware ICI Reduction in MIMO-OFDM Downlinks for High-speed Railway Communication Systems
Jiaxun Lu, Xuhong Chen, Shanyun Liu +1
High mobility may destroy the orthogonality of subcarriers in OFDM systems, resulting in inter- carrier interference (ICI), which may greatly reduce the service quantity of high-sp…

Position-aided Large-scale MIMO Channel Estimation for High-Speed Railway Communication Systems
Tao Li, Xiaodong Wang, Pingyi Fan +1
We consider channel estimation for high-speed railway communication systems, where both the transmitter and the receiver are equipped with large-scale antenna arrays. It is known t…
