Abstract
A wireless communication method for transmitting data signals of first and second users using first and second subcarrier groups, respectively, and transmitting pilot signals of the first and second users by multiplexing the pilot signals to the data signals, including allocating the pilot signals of the first and second users to different frequencies, where each of the pilot signals is generated based on Zadoff-Chu sequence; and mapping subcarrier components of the pilot signals so that one or more subcarrier components of higher frequencies and one or more subcarrier components of lower frequencies in the transmission band become identical, in regard to the pilot signals of each of the first and second users.
