In high-speed railway (HSR) communication systems, distributed antenna is usually employed to support frequent handover and enhance the signal to noise ratio to user equipments. In…
Low-complexity Location-aware Multi-user Massive MIMO Beamforming for High Speed Train Communications
Xuhong Chen, Pingyi Fan
Massive Multiple-input Multiple-output (MIMO) adaption is one of the primary evolving objectives for the next generation high speed train (HST) communication system. In this paper,…
Massive MIMO Beam-forming for High Speed Train Communication: Directivity vs Beamwidth
Xuhong Chen, Jiaxun Lu, Pingyi Fan
High-mobility adaption and massive Multiple-input Multiple-output (MIMO) application are two primary evolving objectives for the next generation high speed train communication syst…
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…
