Abstract  Abstract

The invention relates to a method of transmitting a broadcasting signal the method comprising:
encoding Physical Layer Pipe data by a low-density parity-check code LDPC encoding scheme;
building a signal frame including a preamble and a payload the preamble including a P1 symbol and P2 symbols wherein the encoded PLP data is included in the payload and the P2 symbols; and
transmitting the signal frame via at least one radio frequency RF channel

wherein the P1 symbol includes an effective portion and a cyclic prefix obtained by frequency-shifting a first portion of the effective portion and a cyclic suffix obtained by frequency-shifting a second portion of the effective portion.
