Abstract
The present invention provides a method of transmitting broadcast signals. The method includes, encoding, by an encoder, PLP (Physical Layer Pipe) data; time interleaving, by a time interleaver, the encoded PLP data; frame mapping, by a framer, the time interleaved PLP data onto at least one signal frames; frequency interleaving, by a frequency interleaver, data in the at least one signal frames; and waveform modulating, by a waveform module, the frequency interleaved data in the at least one signal frame and transmitting, by the waveform module, broadcast signals having the modulated data, wherein the frequency interleaving is conducted according to an interleaving mode, wherein the interleaving mode is determined based on a FFT (Fast Fourier Transform) size.
