METHOD AND APPARATUS FOR RELIEVING DOPPLER BROADENING IN WIRELESS ACCESS SYSTEM THAT SUPPORTS SUPER HIGH FREQUENCY BAND |
摘要 |
The present invention provides methods for relieving effective Doppler broadening in performing pin-point beamforming and provides apparatuses for supporting the methods, wherein the methods and the apparatuses are used in a wireless access system that supports a super high frequency band. The method for relieving Doppler broadening in a wireless access system that supports a super high frequency band according to one embodiment of the present invention may comprise the steps of: receiving a downlink signal at a receiving end; estimating a Doppler spectrum for the downlink signal received at the receiving end; and calculating a carrier wave shift value based on the Doppler spectrum estimated at the receiving end. |
