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 on a second broadcast signal, respectively; a MIMO decoder which performs MIMO decoding on the OFDM demodulated first broadcast signal and the OFDM demodulated second broadcast signal to output a first signal and a second signal; a first frequency deinterleaver and a second frequency deinterleaver which deinterleave the first signal and the second signal outputted from the MIMO decoder, respectively, in a frequency domain; and a frame parser which parses frame structures of the first signal and of the second signal outputted from the MIMO decoder, and which merges the first signal and the second signal outputted from the MIMO decoder in order to output a third signal.
