    Abstract: The present disclosure relates to a channel estimation method of a wireless communication device. The channel estimation method includes descrambling a pilot signal having a unit symbol, dividing the descrambled pilot signal, and estimating a channel value of the wireless communication device. The descrambled pilot signal may be divided into a plurality of frequency resources with a first frequency resource and a second frequency resource and generating a first signal chunk with the first frequency resource and a second signal chunk with the second frequency resource. The channel value of the wireless communication device may be estimated based on the first signal chunk and the second signal chunk.
