Abstract
Disclosed herein are a gateway-signaling method for Multiple-Input Single-Output (MISO) operation and an apparatus for the same. An apparatus for transmitting a broadcast signal according to an embodiment of the present invention includes a predistortion unit for performing predistortion for decorrelating signals corresponding to transmitters using the number of transmitters used for MISO and a transmitter coefficient index that are identified using a timing and management packet transmitted through a Studio-to-Transmitter Link (STL), thereby generating a pre-distorted signal; and an RF signal generation unit for generating an RF transmission signal using the pre-distorted signal corresponding to the transmitter coefficient index.
