Channel information prediction system and channel information prediction method
Abstract:
Provided is a channel information prediction system (10) which calculates a MIMO CSI prediction value as a predicted value of the MIMO CSI in the future by using the MIMO CSI and the transformation matrix indicating a transmission path characteristic between a transmitter (100) and a receiver (200) in an multi-antenna transmission system (1) using an antenna array formed by transmission antennas (#1 to #T) or reception antennas (#1 to #R) in the transmitter (100) and the receiver (200). The channel information prediction system (10) calculates the transformation matrix according to an array response or an array weight of the antenna array correlated with the arrival direction or the departure direction by using a direction estimation technique for estimating the arrival direction or the departure direction of the radio signal.
