    Abstract: A receiving apparatus includes: a first decoder configured to decode a signal transmitted through a first layer from a layered division multiplexing (LDM) signal using a parity check matrix to generate low density parity check (LDPC) information word bits and parity bits; an encoder configured to encode the LDPC information word bits, generated by decoding the signal transmitted through the first layer, using the parity check matrix to generate parity bits corresponding only to preset columns in the parity check matrix; and a second decoder configured to decode a signal obtained by removing, from the LDM signal, a signal corresponding to the LDPC information word bits generated by decoding the signal transmitted through the first layer, the parity bits generated by the encoder, and the parity bits generated by the first decoder except the parity bits generated by the encoder, thereby to generate information word bits transmitted through a second layer.

    Abstract: An illumination device includes a conversion unit that controls an emission direction of light emitted from a light-emitting unit included in the illumination device. The conversion unit includes a ball-shaped main body, and may be formed between an upper body, which includes the light-emitting unit, and a lower body. An assembly unit may be formed in the upper body to couple the conversion unit, and the light emission direction may be appropriately controlled by controlling the shape of the ball-shaped main body.

    Abstract: A receiving apparatus is provided. The receiving apparatus includes: a receiver configured to receive an input signal including a transmission frame which includes a bootstrap, a preamble, and a payload; a bootstrap detector configured to detect the bootstrap based on a correlation between the input signal and a reference signal which is pre-stored; and a signal processor configured to signal-process the preamble based on the detected bootstrap and signal-process the payload based on the signal-processed preamble, and the bootstrap detector is configured to determine the correlation by quantizing at least one of the input signal and the reference signal and then multiplexing the input signal and the reference signal at least one of which is quantized. Accordingly, an area occupied by hardware and cost can be reduced and loss of performance can be minimized.

    Abstract: A channel decoding method is provided. The method includes storing, in a memory, a set of first log likelihood ratio (LLR) values corresponding to bits of a codeword generated by modulation of a channel-encoded signal; changing, into a preset value, at least one LLR value corresponding to previously defined bits of the codeword from among the set of the first LLR values, to generate a set of second LLR values; and performing forward error correction (FEC) based on the set of the second LLR values and an FEC code, to estimate the bits of the codeword, in which the FEC code comprises a constraint code for constricting a previously defined structural correlation between the bits of the codeword.
