摘要: 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.

摘要: 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.
