Multipath Extraction Based UL/DL Channel Estimation for FDD Massive MIMO-OFDM Systems

Multipath Extraction Based UL/DL Channel Estimation for FDD Massive MIMO-OFDM Systems

In this paper, we propose a multipath extraction based uplink/downlink channel estimation scheme for wideband massive multiple-input multiple-output (MIMO) systems, where orthogonal frequency division multiplexing (OFDM) is adopted and the beam squint effect is considered. Firstly, we investigate th...
