CHANNEL ESTIMATION METHOD AND APPARATUS FOR USE IN WIRELESS COMMUNICATION SYSTEM

摘要

A channel estimation method includes receiving signals at Resource Elements (REs) designated for reference signals, converting the received signals to time-domain entries using a matched filter, organizing the entries output from the matched filter into groups by delay, determining whether an energy sum of the entries of each group is greater than a predetermined threshold, and selecting the entries belonging to the group of which the energy sum is greater than the threshold value into a candidate group for channel estimation.

1. A channel estimation method of a terminal, the method comprising:
receiving signals at resource elements (REs) designated for reference signals; converting the received signals to time-domain entries using a matched filter; organizing entries output from the matched filter into groups by delay; determining whether an energy sum of entries of each group is greater than a first threshold; and selecting the entries belonging to a group of which the energy sum is greater than the first threshold into a candidate group for channel estimation.
