APPARATUS AND METHOD FOR SENDING AND RECEIVING BROADCAST SIGNALS

摘要

Disclosed herein is a broadcast signal receiver. The broadcast signal receiver according to an embodiment of the present invention includes a synchronization and demodulation module configured to perform detection and OFDM demodulation on a received broadcast signal, a frame parsing and deinterleaving module configured to parse and deinterleave the signal frame of the broadcast signal, a demapping and decoding module configured to convert the data of at least one Physical Layer Pipe (PLP) of the broadcast signal into a bit domain and to FEC-decode the PLP data, and an output processing module configured to receive the data of the at least one PLP and to output the received data in a data stream form.

1. A broadcast signal receiver, comprising:
a Fast Fourier Transform (FFT) module configured to Orthogonal Frequency Division Multiplexing (OFDM)-demodulate a received broadcast signal; a pilot detector configured to detect pilots included in the broadcast signal; a frame parsing module configured to parse a signal frame of the broadcast signal, the signal frame comprising a preamble and at least one subframe; a demapping and decoding module configured to convert Physical Layer Pipe (PLP) data of the broadcast signal into a bit domain and to Forward Error Correction (FEC)-decode the PLP data; and an output processing module configured to receive the PLP data and to output a data stream, wherein the subframe comprises data symbols and at least one Subframe Boundary Symbol (SBS), and the SBS comprises data carriers and subframe boundary pilots, and wherein the data symbols of the subframe comprises Scattered Pilots (SPs), amplitude of the SPs is determined based on an SP boosting parameter indicating a power boosting level of the SPs, and amplitude of the subframe boundary pilots is determined based on the SP boosting parameter.
