Abstract
Disclosed herein is a broadcast signal receiver. A broadcast signal receiver according to an embodiment of the present invention includes a synchronization and demodulation unit configured to perform signal detection and OFDM demodulation on a received signal, a frame parser configured to parse the signal frame of the received signal, a time deinterleaving unit configured to deinterleave LDM data, a first demapping/decoding unit configured to obtain the data of a core layer by demapping and FEC-decoding the LDM data, an interference removal unit configured to remove the core layer data from the LDM data and to output the data of an enhanced layer, and a second demapping/decoding unit configured to demap and FEC-decode the enhanced layer data.
