APPARATUS AND METHOD FOR SENDING AND RECEIVING BROADCAST SIGNALS

摘要

Disclosed is a broadcast signal receiver. The broadcast signal receiver includes a synchronization and demodulation unit configured to perform signal detection and OFDM demodulation on a reception signal comprising layer division multiplexing (LDM) data, a frame parsing/deinterleaving unit configured to parse the signal frame of the reception signal and to deinterleave the LDM data, a first demapping/decoding unit configured to obtain the data of a first layer by demapping and forward error correction (FEC)-encoding the LDM data, an interference removal unit configured to remove the data of the first layer from the LDM data and to output the data of a second layer, and a second demapping/decoding unit configured to demap and FEC-decode the data of the second layer.
