  • Patent number: 10454500
    Abstract: A bit interleaver, a bit-interleaved coded modulation (BICM) device and a bit interleaving method are disclosed herein. The bit interleaver includes a first memory, a processor, and a second memory. The first memory stores a low-density parity check (LDPC) codeword having a length of 16200 and a code rate of 2/15. The processor generates an interleaved codeword by interleaving the LDPC codeword on a bit group basis. The size of the bit group corresponds to a parallel factor of the LDPC codeword. The second memory provides the interleaved codeword to a modulator for 256-symbol mapping.

  • Patent number: 10454536
    Abstract: Disclosed herein are a method for transceiving a broadcast signal using a combination of multiple antenna schemes with layered division multiplexing and an apparatus for the method. A method for receiving a broadcast signal includes generating received signals based on signals that are received through multiple receiving antennas, estimating channels between the receiving antennas and transmitting antennas, restoring a core-layer signal corresponding to the received signals, and restoring an enhanced-layer signal based on a cancellation process, wherein the cancellation process corresponds to the core-layer signal and is separately performed for the individual receiving antennas.
