Abstract
The present invention relates to a transmitter in a frequency division multiple access communication system. The transmitter generates a plurality of pilot symbols, and groups the plurality of pilot symbols into a plurality of groups according to a location of a subcarrier. In addition, the transmitter inverse fast Fourier transforms the pilot symbol in each group, and sequentially outputs a first pilot symbol sequence corresponding to each group. The transmitter generates a plurality of pilot blocks respectively corresponding to the plurality of groups, and converts the first pilot symbol sequence of each group into a second pilot symbol sequence of a corresponding pilot block among the plurality of pilot blocks.
