Location-aware ICI Reduction in MIMO-OFDM Downlinks for High-speed Railway Communication Systems

12 Jul 2016 Lu Jiaxun Chen Xuhong Liu Shanyun Fan Pingyi

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-speed railway (HSR) wireless communications. This paper focuses on ICI mitigation in the HSR downlinks with distributed transmit antennas.For such a system, its key feature is that the ICIs are caused by multiple carrier frequency offsets corresponding to multiple transmit antennas...
