APPARATUS AND METHOD FOR SENDING AND RECEIVING BROADCAST SIGNALS

摘要

A broadcast signal receiver is disclosed. A broadcast signal receiver according to an embodiment of the present invention comprises a constellation mapper for symbol-demapping by using the signaling information as LLR values; a bit deinterleaver for bit multiplexing and block deinterleaving of the signaling information; an FEC decoder for FEC decoding the signaling information; and a descrambler for descrambling the signaling information.

主权项

1. A broadcast signal receiver for processing a broadcast signal including signaling information, the broadcast signal receiver, comprising:
a constellation demapper for symbol-demapping the signaling information to LLR values; a bit deinterleaver for bit multiplexing and block deinterleaving the signaling information; an FEC decoder for FEC decoding the signaling information; and a descrambler for descrambling the signaling information, wherein the FEC decoder further comprises a zero inserting/parity inserting unit for inserting shortened zero bits and punctured parity bits into the signaling information; an LDPC decoder for LDPC decoding the signaling information; and a BCH decoder for removing zero bits of the signaling information and BCH decoding the signaling information.
