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 transmitter comprises: an input signal generating unit which generates a first input signal and a second input signal; a MIMO encoder which performs MIMO processing on the first input signal and on the second input signal to output a first transmission signal and a second transmission signal; and a first OFDM generator and a second OFDM generator which perform OFDM modulation on the first transmission signal and on the second transmission signal, respectively, wherein said MIMO processing is performed by applying a MIMO matrix to the first input signal and to the second input signal.
