Abstract
Official abstract text for this publication.
A method for transmitting and receiving a signal and an apparatus for transmitting and receiving a signal are disclosed. The method for receiving the signal includes receiving (S 210 ) the signal in a first frequency band, identifying (S 220 ) a first pilot signal including, a cyclic prefix obtained by frequency-shifting a first portion of an useful portion of the first pilot signal and a cyclic suffix obtained by frequency-shifting a second portion of the useful portion of the first pilot signal from the received signal, demodulating (S 220 ) a signal frame including a physical layer pipe (PLP) to which a service stream is converted, by an orthogonal frequency division multiplexing (OFDM) scheme, using information set in the first pilot signal, parsing (S 230 ) the signal frame and obtaining the PLP and obtaining (S 240 ) the service stream from the PLP.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of transmitting a broadcast signal, the method comprising: building a signal frame based on service data; modulating the signal frame according to an orthogonal frequency division multiplexing (OFDM) scheme; inserting a symbol into a beginning part of the modulated signal frame; and transmitting the broadcast signal including the signal frame and the inserted symbol, wherein the symbol comprises an effective portion, a cyclic prefix obtained…
