Title:
BROADCAST SIGNAL TRANSMITTER AND RECEIVER, AND BROADCAST SIGNAL TRANSMITTING AND RECEIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/096738
Kind Code:
A2
Abstract:
According to one embodiment of the present invention, a broadcast signal transmitter comprises: a symbol mapper which symbol-maps data into a M-QAM type; an input signal generating unit which generates a first M-QAM-type input signal and a second M-QAM-type 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 M*M-QAM-type transmission signal and a second M*M-QAM-type 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.
