Provided is a broadcast signal transmitting method including: generating a first bitstream including encoded data; generating a second bitstream by adding zero bits to the first bitstream, based on a difference between a modem data rate and a codec data rate; generating a third bitstream by encoding the second bitstream by using zero padding information about the zero bits; and transmitting a carrier signal generated by modulating the third bitstream.

Channel encoding and decoding methods and apparatuses using zero bit padding

A method and apparatus for generating a preamble symbol in an Orthogonal Frequency Division Multiplexing (OFDM) system by generating a first main body sequence in a time domain by performing an inverse fast Fourier transform (IFFT) on a preset sequence in a frequency domain, generating a first postfix by copying samples in a preset section in the first main body sequence, generating a first prefix by copying samples in at least a portion of a section remaining by excluding the preset section from the first main body sequence, and generating a plurality of symbols, based on a combination of the first main body sequence, the first prefix, and the first postfix.

Apparatus and method for generating and detecting preamble symbol

A transmitting apparatus is provided. The transmitting apparatus includes: an L1 signaling generator configured to generate L1 signaling including first information and second information; a frame generator configured to generate a frame including a payload including a plurality of sub frames; and a signal processor configured to insert a preamble including the L1 signaling in the frame and transmit the frame. The first information includes information required for decoding a first sub frame among the plurality of sub frames. Therefore, a processing delay in a receiving apparatus is reduced.

Transmitting apparatus, receiving apparatus, and control methods thereof

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.

Receiving apparatus and control method thereof

A transmitting apparatus is provided. The transmitting apparatus includes: an Lsignaling generator configured to generate Lsignaling including first information and second information; a frame generator configured to generate a frame including a payload including a plurality of sub frames; and a signal processor configured to insert a preamble including the Lsignaling in the frame and transmit the frame. The first information includes information required for decoding a first sub frame among the plurality of sub frames. Therefore, a processing delay in a receiving apparatus is reduced.
