BROADCAST SIGNAL TRANSMITTING DEVICE, BROADCAST SIGNAL RECEIVING DEVICE, BROAD CAST SIGNAL TRANSMITTING METHOD, AND BROADCAST SIGNAL RECEIVING METHOD

摘要

A broadcast signal receiving device according to an embodiment of the present invention may comprise: a receiving unit for receiving broadcast signals; a demodulator for demodulating received broadcast signals through an OFDM (Orthogonal Frequency Division Multiplex) technique; a frame parser for parsing signal frames from demodulated broadcast signals; a MIMO processor for MIMO (Multi Input Multi Output) processing service data including signal frames on the basis of a rotation matrix having a rotation angle; a demapper for demapping MIMO-processed service data; and a decoder for decoding the demapped service data.
