<p>The invention relates to a method for receiving a broadcast signal, the method comprising: receiving a broadcast signal including physical layer pipe, PLP, data symbols and a first pilot, P1, symbol inserted to at a beginning part of a frame of the broadcast signal, the P1 symbol having a structure including a first, second and third portions, wherein the second portion is an effective portion of the P1 symbol, the first portion carries frequency-shifted version of a first part of the second portion and the third portion carries frequency-shifted version of a second part of the second portion; demodulating the broadcast signal by an orthogonal frequency divisional multiplexing scheme; demapping PLP data symbols in the broadcast signal to PLP data bits; and decoding the PLP data bits for forward error correction, FEC. There is further disclosed an interrelated apparatus.</p> |
