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 64800 and a code rate of 5/15. 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 4096-symbol mapping.

Abstract: Systems and methods which provide for accurate decoding of a received channel signal when station identifier information is unknown. Embodiments accurately decode a physical downlink control channel (PDCCH), such as to obtain downlink control information (DCI), without knowing radio network temporary identifier (RNTI) information. An unknown station identifier information (USII) of embodiments uses redundancy reduction-based error checking (performing error checking between data decoded from a candidate control channel data block containing redundant data and a portion of that candidate control channel data block containing redundancy reduced data) for implementing decoding when station identifier information is unknown. Embodiments of a USII decoder may use a power detection technique for identifying candidate control channel data blocks used in redundancy reduction-based error checking operation.
