Abstract:
Disclosed is a Doppler distribution measurement method comprising: receiving a plurality of receive signals that arrive via different RE sets in different paths; measuring CFO values of the plurality of receive signals; selecting the two receive signals in which the difference in value between the CFO values are the greatest, from among the plurality of receive signals; and determining a Doppler shift difference between the selected two receive signals a an effective Doppler distribution.
