Abstract: A transmitter includes a frame generator which generates a plurality of frames each of which includes a preamble symbol and a data symbol, a pilot inserter which inserts a plurality of first pilots in the preamble symbol according to a predetermined first arrangement pattern and inserts a plurality of second pilots in a data symbol according to a second arrangement pattern, and a transmitting unit which transmits the plurality of frames in which the first and second pilots are inserted. Accordingly, a memory needed to store pilots may be reduced and precise synchronization may be performed based on an extended number of pilots.
