Abstract
The present invention provides a method for channel estimation used in a receiver of a multi-carrier communication system, including: receiving a multi-carrier symbols from a transmitter of the multi-carrier communication system; and obtaining channel information of sub-carriers carrying data of the multi-carrier symbols, using selectively time direction interpolation and frequency direction interpolation for channel information of a plurality of scatter pilots of the multi-carrier symbols.
