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 M*M-QAM-type broadcast signal and on a second M*M-QAM-type broadcast signal, respectively; a MIMO decoder which performs MIMO decoding on the first OFDM-demodulated broadcast signal and on the second OFDM-demodulated broadcast signal to output a first M-QAM-type signal and a second M-QAM-type signal; a first frequency deinterleaver and a second frequency deinterleaver which deinterleave the first M-QAM-type signal and the second M-QAM-type signal, respectively, in a frequency domain; and a frame parser which parses frame structures of the first M-QAM-type signal and of the second M-QAM-type signal, and merges the first M-QAM-type signal and the second M-QAM-type signal so as to output a third signal. |
