BROADCAST SIGNAL TRANSMITTER AND RECEIVER, AND BROADCAST SIGNAL TRANSMITTING AND RECEIVING METHOD

摘要

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 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 frame structures of the first deinterleaved broadcast signal and the second deinterleaved broadcast signal, respectively; a first time deinterleaver and a second time deinterleaver which deinterleave the first frame-parsed broadcast signal and the second frame-parsed broadcast signal, respectively, in a time domain; and 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.
