Intelligent CSI feedback method for fast time-varying FDD massive MIMO system

Show other versions (1)

In the frequency division duplexing (FDD) massive multiple-input multiple-output (MIMO) system, the channel state information (CSI) matrix existed noise caused by the wireless channel interference and the time correlation caused by Doppler shift.Because of these effects, the communication system cou...
