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 so as 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 setting a code of the second input signal in accordance with the value of the first input signal and applying a MIMO matrix, and said MIMO matrix adjusts the power of the first input signal and the power of the second input signal using a parameter a, and said parameter a is set to different values in accordance with the modulation types of the first input signal and of the second input signal. |
