Abstract: A broadcast signal transmitter is provided that includes an Forward Error Correction (FEC) encoder configured to error correction process Physical Layer Pipe (PLP) data; a bit interleaver configured to bit interleave the PLP data; a framer configured to generate a signal frame comprising the PLP data, the signal frame comprising a preamble and at least one subframe; a pilot inserter configured to insert Scattered Pilots (SPs) into the signal frame; and an Inverse Fast Fourier Transform (IFFT) modulator configured to perform Orthogonal Frequency Division Multiplexing (OFDM)-modulation on the signal frame. An SP pattern of the SPs is defined by Dx and Dy, the Dx being a separation of pilot bearing carriers in a frequency direction and the Dy being a number of symbols forming one scattered pilot sequence in a time direction. The amplitude of the SPs is determined from a SP boosting parameter and the SP pattern of the SPs.
