Abstract

According to one embodiment of the present invention, a broadcast signal receiver comprises: a first OFDM demodulator and a second OFDM demodulator which perform OFDM demodulation on a first broadcast signal and on a second broadcast signal, respectively; a first frequency deinterleaver and a second frequency deinterleaver which deinterleave the first OFDM-demodulated broadcast signal and the second OFDM-demodulated broadcast signal, respectively, in a frequency domain; a first frame parser and a second frame parser which parse the frame structures of the first deinterleaved broadcast signal and of the second deinterleaved broadcast signal, respectively; a first time deinterleaver and a second time deinterleaver which deinterleave the frame-parsed first broadcast signal and the frame-parsed second broadcast signal, respectively, in a time domain; a MIMO decoder which performs MIMO decoding on the first time-deinterleaved broadcast signal and on the second time-deinterleaved broadcast signal to output a first signal and a second signal; and a merger which merges the first signal and the second signal outputted by the MIMO decoder.
