Apparatus and method for transmitting and receiving data in a communication or broadcasting system using linear block code

摘要

Provided is a method for transmitting data in a communication or broadcasting system using a linear block code by generating a codeword by encoding input information data bits, interleaving the codeword; outputting modulation signal-constituting bits by bit-mapping the interleaved codeword using a bit-mapping table predetermined depending on a modulation scheme and a coding rate, outputting a modulation signal by modulating the modulation signal-constituting bits and transmitting the modulation signal via a transmit antenna.

1. A method for transmitting data in a communication or broadcasting system, comprising:
generating a codeword by encoding input information data bits; interleaving the codeword; demultiplexing the interleaved codeword using a bit-mapping table that is determined based on a modulation scheme and a coding rate; outputting a modulation signal by modulating the demultiplexed bits; and transmitting the modulation signal,wherein when the modulation scheme is 16-Quadrature Amplitude Modulation (16-QAM) and the coding rate includes one of ⅕ and ¼, the bit-mapping table is defined as:16-QAMInput bit number01234567Output bit number17054263where the “input bit number” represents an input bit number di in the interleaved codeword vd, and the “output bit number” represents a demultiplexed substream value e in the demultiplexed bits be,d0.
