    摘要: An apparatus is provided for transmitting a signal in a communication system using a Low Density Parity Check (LDPC) code. A controller determines a number of ‘0’s to be inserted in information data according to a first coding rate to be applied when generating the information data into an LDPC code, and determines the number of ‘0’s to be removed from the LDPC code. A ‘0’ inserter inserts ‘0s’ in the information data according to control of the controller. An LDPC encoder generates the LDPC code by encoding the ‘0’-inserted signal according to a first parity check matrix. A ‘0’ remover removes the inserted ‘0’s from the LDPC code.

    摘要: Disclosed is a method for transmitting a signal in a signal transmission system, which includes demultiplexing a bit stream to be transmitted into a first bit stream and a second bit stream; generating a first coded bit stream by coding the first bit stream according to a first coding rate and generating a second coded bit stream by coding the second bit stream according to a second coding rate; and generating a coded symbol by concatenating the first coded bit stream and the second coded bit stream.
